SMB3: Honor 'posix' flag for multiuser mounts
[ Upstream commit 5391b8e1b7b7e5cfa2dd4ffdc4b8c6b64dfd1866 ]
The flag from the primary tcon needs to be copied into the volume info
so that cifs_get_tcon will try to enable extensions on the per-user
tcon. At that point, since posix extensions must have already been
enabled on the superblock, don't try to needlessly adjust the mount
flags.
Fixes: ce558b0e17f8 ("smb3: Add posix create context for smb3.11 posix mounts")
Fixes: b326614ea215 ("smb3: allow "posix" mount option to enable new SMB311 protocol extensions")
