SMB 3.0 and 3.0.2 require aes-128-ccm, so we need to reject them unless
'client smb3 encryption algorithms' allows them.

It checks that the resulting algorithms (most likely for
dialects < 3.1.1) are actually allowed.

The motivation is to get the same error responses as a windows server.
We already fallback to smb2srv_session_lookup_global() in other places
where we don't have a valid session in the current smbd process.
If signing is failing while verifying a session setup request,
we should do the same if we don't have a valid channel binding
for the connection yet.

There might be other places than smb2srv_update_crypto_flags(), which
may call smbXsrv_session_update() with a fake session, they should
return in error instead of segfaulting.

triggers (at least in samba) a different code path compaired
