We may first learn our fsid from any of the mon, osd, or mds maps
(whichever the monitor sends first). Consolidate checks in a single
helper. Initialize the client debugfs entry then, since we need the
fsid (and global_id) for the directory name.
Also remove dead mount code.

Basic state information is available via /sys/kernel/debug/ceph,
including instances of the client, fsids, current monitor, mds and osd
maps, outstanding server requests, and hooks to adjust debug levels.
