We used %llu as conversion specifier which results in a decimal number

While at it, I'll change %llu to the terse %ju.

The STATUS_SESSION_EXPIRED error was returned unencrypted,
if the request was encrypted.
If clients use SMB3 encryption and the kerberos authenticated session
expires, clients disconnect the connection instead of doing a reauthentication.
From https://blogs.msdn.microsoft.com/openspecification/2012/10/05/encryption-in-smb-3-0-a-protocol-perspective/
The sender encrypts the message if any of the following conditions is
satisfied:
- If the sender is sending a response to an encrypted request.
- If Session.EncryptData is TRUE and the request or response being
sent is not NEGOTIATE.
- If Session.EncryptData is FALSE, the request or response being sent
is not NEGOTIATE or SESSION_SETUP or TREE_CONNECT, and
<TreeConnect|Share>.EncryptData is TRUE.
[MS-SMB2] 3.3.4.1.4 Encrypting the Message
If Connection.Dialect belongs to the SMB 3.x dialect family and
Connection.ClientCapabilities includes the SMB2_GLOBAL_CAP_ENCRYPTION
bit, the server MUST encrypt the message before sending, if any of the
following conditions are satisfied:
- If the message being sent is any response to a client request for which
Request.IsEncrypted is TRUE.
- If Session.EncryptData is TRUE and the response being sent is not
SMB2_NEGOTIATE or SMB2 SESSION_SETUP.
- If Session.EncryptData is FALSE, the response being sent is not
SMB2_NEGOTIATE or SMB2 SESSION_SETUP or SMB2 TREE_CONNECT, and
Share.EncryptData for the share associated with the TreeId in the SMB2
header of the response is TRUE.
The server MUST encrypt the message as specified in section 3.1.4.3,
before sending it to the client.

The SMBnegprot response from the server contains the DialectIndex of the
selected protocol from the client's request message. Currently, if no
protocol is selected, the server is responding with a DialectIndex=zero,
which is a valid index (PROTOCOL_CORE by default). The Windows spec, and
historically the code, should return DialectIndex=0xffff if no protocol
is chosen. The following commit changed it recently (presumably
inadvertently), so that it now returns DialectIndex=zero.
06940155f3 s3:smbd: Fix size types in reply_negprot()
This results in somewhat confusing error messages on the client side:
ERROR(runtime): uncaught exception - (3221225997, 'The transport
connection has been reset.')
or, when signing is configured as mandatory:
smbXcli_negprot: SMB signing is mandatory and the selected protocol
level (1) doesn't support it.
ERROR(runtime): uncaught exception - (3221225506, '{Access Denied} A
process has requested access to an object but has not been granted those
access rights.')
This patch restores the old behaviour of returning 0xffff.

This avoids a race in durable handle reconnects if the reconnect comes
in while the old session is still in the tear-down phase.
The new session is supposed to rendezvous with and wait for destruction
of the old session, which is internally implemented with
dbwrap_watch_send() on the old session record.
If the old session deletes the session record before calling
file_close_user() which marks all file handles as disconnected, the
durable handle reconnect in the new session will fail as the records are
not yet marked as disconnected which is a prerequisite.
