[VLAN]: Make sure bonding packet drop checks get done in hwaccel RX path.
Since __vlan_hwaccel_rx() is essentially bypassing the
netif_receive_skb() call that would have occurred if we did the VLAN
decapsulation in software, we are missing the skb_bond() call and the
assosciated checks it does.
Export those checks via an inline function, skb_bond_should_drop(),
and use this in __vlan_hwaccel_rx().
