libceph: osd_client: don't drop reply reference too early
In ceph_osdc_release_request(), a reference to the r_reply message is dropped. But just after that, that same message is revoked if it was in use to receive an incoming reply. Reorder these so we are sure we hold a reference until we're actually done with the message.
