Description

http://pulpito.ceph.com/gregf-2016-01-12_23:29:42-fs-greg-fs-speculative---basic-mira/26556

The asok handler is correct to be taking the lock, but it's in conflict with initialization where we do MDSDaemon::mds_lock -> AdminSocket::m_lock.

There are other commands that take the lock (i.e. we already had a bug, but the new status command gets called frequently enough to expose it, whereas the others not so).
