Stanislav Fomichev 0d6ae25da5 bpf: Move skb->len == 0 checks into __bpf_redirect ...

[ Upstream commit 114039b342014680911c35bd6b72624180fd669a ]

To avoid potentially breaking existing users.

Both mac/no-mac cases have to be amended; mac_header >= network_header
is not enough (verified with a new test, see next patch).
