netfilter: nft_payload: fix wrong mac header matching
commit d351c1ea2de3e36e608fc355d8ae7d0cc80e6cd6 upstream.
mcast packets get looped back to the local machine.
Such packets have a 0-length mac header, we should treat
this like "mac header not set" and abort rule evaluation.
As-is, we just copy data from the network header instead.
