glusterfsd: rpcsvc actors must return success after an attempt to submit reply
rpcsvc attempts to send "error reply" using the req object. If actor has already performed rpcsvc_submit_generic, then req is destroyed. So if the actor returned -1 (RPCSVC_ACTOR_ERROR) on failing to submit reply, then req would be 'free'd' twice and will result in a crash eventually.
