Revert "mds: trigger tableserver active/recovery hook even for self"

This reverts commit 968c6c0c9408b33904041e5ddbd9ea738e831713.

This will trigger the 'ready' message twice when we restart, because we
will trigger in both recovery_done() and handle_mds_recovery().

mds: initialize tableservers/clients on mds creation

The handle_mds_recovery(who) path initializes the anchorclients by having
the server send a 'ready' message on recovery when the server is active
and a peer becomes active.  Similarly, recovery_done() does the same when
the server becomes active.  However, this misses the creation path.  Handle
that explicitly in boot_create.
