From: Bob Pearson <rpearson@xxxxxxx>
In send_atomic_ack() in rxe_resp.c there is code copying ack_pkt
into the skb->cb[]. This doesn't do anything useful because the
cb[] is not used in the transmit path by the rxe driver.
Remove this code.
Fixes: 4c93496f18ce ("IB/rxe: do not copy extra stack memory to skb")
