Move the MAC entry point to label ethernet-sourced mbufs with a MAC label
from the network interface earlier in ether_input(). At some point
(no fingers pointed), things were restructured and the labeling operation
moved later. This wasn't a problem as BPF_MTAP() relies on the ifnet
label not the mbuf label, but there might have been other problems.
