Jeff Layton 603d4bcc0f ceph: skip existing superblocks that are blocklisted or shut down when mounting 
commit 98d0a6fb7303a6f4a120b8b8ed05b86ff5db53e8 upstream.

Currently when mounting, we may end up finding an existing superblock
that corresponds to a blocklisted MDS client. This means that the new
mount ends up being unusable.

If we've found an existing superblock with a client that is already
blocklisted, and the client is not configured to recover on its own,
fail the match. Ditto if the superblock has been forcibly unmounted.

While we're in here, also rename "other" to the more conventional "fsc".
