ceph: fix message revocation
A message can be on a queue (pending or sent), or out_msg (sending), or
both. We were assuming that if it's not on a queue it couldn't be out_msg,
but that was false in the case of lossy connections like the OSD. Fix
ceph_con_revoke() to treat these cases independently. Also, fix the
out_kvec_is_message check to only trigger if we are currently sending
_this_ message.
This fixes a GPF in tcp_sendpage, triggered by OSD restarts.
