smb3: fix problem remounting a share after shutdown
commit 716a3cf3 upstream. xfstests generic/392 showed a problem where even after a shutdown call was made on a mount, we would still attempt to use the (now inaccessible) superblock if another mount was attempted for the same share. Reported-by:David Howells <dhowells@redhat.com> Reviewed-by:
