If the tcp connection drops and we reconnect to reestablish a stateful session (with the mds), we need to resend previously sent (and possibly received) messages with the _same_ seq # so that they can be dropped on the other end if needed. Only assign a new seq once after the message is queued. Signed-off-by: Sage Weil <sage@newdream.net>
