Add a new private API to support the untag drop enable/disable
for specific VF.
Add a flag "untag_drop" in i40e_vsi to help track the untag drop
status, so it prevent error from i40e_aq_remove_vlan when call
rte_pmd_i40e_set_vf_vlan_untag_drop twice.

V2:
- Add a flag "untag_drop" in i40e_vsi to track the untag drop status.
