[CIFS] When mandatory encryption on share, fail mount
When mandatory encryption is configured in samba server on a
share (smb.conf parameter "smb encrypt = mandatory") the
server will hang up the tcp session when we try to send
the first frame after the tree connect if it is not a
QueryFSUnixInfo, this causes cifs mount to hang (it must
be killed with ctl-c). Move the QueryFSUnixInfo call
earlier in the mount sequence, and check whether the SetFSUnixInfo
fails due to mandatory encryption so we can return a sensible
error (EACCES) on mount.
In a future patch (for 2.6.40) we will support mandatory
encryption.
