ceph_con_revoke_message() is passed both a message and a ceph connection. A ceph_msg allocated for incoming messages on a connection always has a pointer to that connection, so there's no need to provide the connection when revoking such a message. Note that the existing logic does not preclude the message supplied being a null/bogus message pointer. The only user of this interface is the OSD client, and the only value an osd client passes is a request's r_reply field. That is always non-null (except briefly in an error path in ceph_osdc_alloc_request(), and that drops the only reference so the request won't ever have a reply to revoke). So we can safely assume the passed-in message is non-null, but add a BUG_ON() to make it very obvious we are imposing this restriction. Rename the function ceph_msg_revoke_incoming() to reflect that it is really an operation on an incoming message.
