Revert "ipvlan: add L2 check for packets arriving via virtual devices"

This reverts commit ace92d0493bf082fb9eb1ada579746a8de9c45d8.

Even though the check added is not that taxing, it's not really needed.
First of all this will be per packet cost and second thing is that the
eth_type_trans() already does this correctly. The excessive scrubbing
in IPvlan was changing the pkt-type skb metadata of the packet which
made it necessary to re-check the mac. The subsequent patch in this
series removes the faulty packet-scrub.
