This isn't worth a bug backport as right now the only flag that
could be overwritten is the UCF_POSIX_PATHNAMES flag, and for
a POSIX connection the client will use posix rename, not an
ntrename.

The "ea support" configuration variable determines whether smbd
should attempt to manipulate extended attributes via SMB protocol.
It does not pertain to the underlying storage and its support for
extended attributes.
get_ea_names_from_file() is being used also by vfs_streams_xattr -
a module which has nothing to do with client-visible extended
attributes. As such, vfs_streams_xattr should be able to operate
irrespective of the value of "ea support".
This patch moves the check for ea support to the callers.

This fixes a regression introduced by commit
f98d10af2a05f0261611f4cabdfe274cd9fe91c0
(smbd: Always use UCF_PREP_CREATEFILE for filename_convert calls to resolve a path for open)
The main problem was that Windows client seem to verify
the access to user.V2\ntuser.ini is rejected with NT_STATUS_ACCESS_DENIED,
using the machine credentials.
Passing UCF_PREP_CREATEFILE to filename_convert() triggers a code path
that implements a dropbox behaviour. A dropbox is a directory with only -wx permissions,
so get_real_filename fails with EACCESS, it needs to list the directory.
EACCESS is ignored with UCF_PREP_CREATEFILE.

Sometimes Windows clients doesn't filter SECINFO_[UN]PROTECTED_[D|S]ACL flags
before sending the security_information to the server.
security_information = SECINFO_PROTECTED_DACL| SECINFO_DACL
results in a NULL dacl being returned from an GetSecurityDecriptor
request. This happens because posix_get_nt_acl_common()
has the following logic:
if ((security_info & SECINFO_DACL) && !(security_info & SECINFO_PROTECTED_DACL)) {
... create DACL ...
}
I'm not sure if the logic is correct or wrong in this place (I guess it's
wrong...).
But what I know is that the SMB server should filter the given
security_information flags before passing to the filesystem.
[MS-SMB2] 3.3.5.20.3 Handling SMB2_0_INFO_SECURITY
...
The server MUST ignore any flag value in the AdditionalInformation field that
is not specified in section 2.2.37.

OWNER_SECURITY_INFORMATION
