smb3: do not attempt cifs operation in smb3 query info error path

smb3: do not attempt cifs operation in smb3 query info error path

commit 1e77a8c204c9d1b655c61751b8ad0fde22421dbb upstream.

If backupuid mount option is sent, we can incorrectly retry
(on access denied on query info) with a cifs (FindFirst) operation
on an smb3 mount which causes the server to force the session close.

We set backup intent on open so no need for this fallback.
