net_sched: fix mirrored packets checksum
[ Upstream commit 82a31b9231f02d9c1b7b290a46999d517b0d312a ] Similar to commit 9b368814b336 ("net: fix bridge multicast packet checksum validation") we need to fixup the checksum for CHECKSUM_COMPLETE when pushing skb on RX path. Otherwise we get similar splats.
