VLAN proto, used in ice XDP hints implementation is stored in ring packet
context. Utilize this value in skb VLAN processing too instead of checking
netdev features.

At the same time, use vlan_tci instead of vlan_tag in touched code,
because VLAN tag often refers to VLAN proto and VLAN TCI combined,
while in the code we clearly store only VLAN TCI.
