macvlan: do not assume mac_header is set in macvlan_broadcast()
which fixed some TX cases but broke the RX case. When handling a
received multicast or broadcast packet, macvlan_broadcast() now reads
the destination address from the wrong place. The packets may then
fail to match the multicast filters that they should. This is fixed
in 4.9.211 by:

macvlan: use skb_reset_mac_header() in macvlan_queue_xmit()
This is a major regression for VM hosts using macvlan/macvtap as
ARP and IPv6 neighbour discovery became quite unreliable.
