Steve French 122f2bd8d3 smb3: do not attempt cifs operation in smb3 query info error path ...

commit 1e77a8c204 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.
