macvlan: use skb_reset_mac_header() in macvlan_queue_xmit()

Browse source 
[ Upstream commit 1712b2fff8c682d145c7889d2290696647d82dab ]

I missed the fact that macvlan_broadcast() can be used both
in RX and TX.

skb_eth_hdr() makes only sense in TX paths, so we can not
use it blindly in macvlan_broadcast()

Fixes: 96cc4b69581d ("macvlan: do not assume mac_header is set in macvlan_broadcast()")
