These functions purpose is to add a new MAC filter correctly, whether we're using VLANs or not. Their goal is to ensure that all active VLANs get the new MAC filter. Rename them so that their intent is clear. They function correctly regardless of whether we have any active VLANs or only have I40E_VLAN_ANY filters. The new names convey how they function in a more clear manner.
