ceph: don't WARN if we're still opening a session to an MDS
If MDSs aren't available while mounting a filesystem, the session state
will transition from SESSION_OPENING to SESSION_CLOSING. And in that
scenario check_session_state() will be called from delayed_work() and
trigger this WARN.
Avoid this by only WARNing after a session has already been established
(i.e., the s_ttl will be different from 0).
Fixes: 62575e270f66 ("ceph: check session state after bumping session->s_seq")
