ceph: skip reconnecting if MDS is not ready
When MDS closed the session the kclient will send to reconnect to
it immediately, but if the MDS just restarted and still not ready
yet, such as still in the up:replay state and the sessionmap journal
logs hasn't be replayed, the MDS will close the session.
And then the kclient could remove the session and later when the
mdsmap is in RECONNECT phrase it will skip reconnecting. But the MDS
will wait until timeout and then evict the kclient.
Just skip sending the reconnection request until the MDS is ready.
