SMB311: Fix reconnect
The preauth hash was not being recalculated properly on reconnect of SMB3.11 dialect mounts (which caused access denied repeatedly on auto-reconnect). Fixes: 8bd68c6e47ab ("CIFS: implement v3.11 preauth integrity") Signed-off-by: Steve French <smfrench@gmail.com> CC: Stable <stable@vger.kernel.org> Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com>
