Clean up. Now that there is only one registration mode, there is only one target "post_send" method: frwr_send(). rpcrdma_post_sends() no longer adds much value, especially since all of its call sites ignore the return code value except to check if it's non-zero. Just have them call frwr_send() directly instead.
