ice: Introduce ice_vlan struct 

Add a new struct for VLAN related information. Currently this holds
VLAN ID and priority values, but will be expanded to hold TPID value.
This reduces the changes necessary if any other values are added in
future. Remove the action argument from these calls as it's always
ICE_FWD_VSI.
