libceph: admit message frames only in CEPH_CON_S_OPEN state

commit a5a373705081d7cc6363e16990e2361b0b362314 upstream.

Similar checks are performed for all control frames, but an early check
for message frames was missing.  process_message() is already set up to
terminate the loop in case the state changes while con->ops->dispatch()
handler is being executed.
