net: skb_reset_mac_len() must check if mac_header was set
Recent discussions show that skb_reset_mac_len() should be more careful.
We expect the MAC header being set.
If not, clear skb->mac_len and fire a warning for CONFIG_DEBUG_NET=y builds.
If after investigations we find that not having a MAC header was okay,
we can remove the warning.
