Subject: act_mirred: clear sender cpu before sending to tx

From: WANG Cong <xiyou.wangcong@gmail.com>

[ Upstream commit d40496a56430eac0d330378816954619899fe303 ]

Similar to commit c29390c6dfee ("xps: must clear sender_cpu before forwarding")
the skb->sender_cpu needs to be cleared when moving from Rx
Tx, otherwise kernel could crash.
