bonding: remove bond_vlan_used()
We're using it currently to verify if we have vlans before getting the tag
from the skb we're about to send. It's useless because the vlan_get_tag()
verifies if the skb has the tag (and returns an error if not), and we can
receive tagged skbs only if we *already* have vlans.
Plus, the current RCUed implementation is kind of useless anyway - the we
can remove the last vlan in the moment we return from the function.
So remove the only usage of it and the whole function.
