ice: Refactor vf->port_vlan_info to use ice_vlan

Browse Source 
The current vf->port_vlan_info variable is a packed u16 that contains
the port VLAN ID and QoS/prio value. This is fine, but changes are
incoming that allow for an 802.1ad port VLAN. Add flexibility by
changing the vf->port_vlan_info member to be an ice_vlan structure.
