This gathers a number of very minor changes:
- use %hu when formatting the a socket address's address family
- null out the ceph_msgr_wq pointer after the queue has been
destroyed
- drop a needless cast in ceph_write_space()
- add a WARN() call in ceph_state_change() in the event an
unrecognized socket state is encountered
- rearrange the logic in ceph_con_get() and ceph_con_put() so
that:
- the reference counts are only atomically read once
- the values displayed via dout() calls are known to
be meaningful at the time they are formatted
