Protocol id for first vlan in Double VLAN Mode (DVM) should be
ICE_VLAN_OF_HW = 16, but for Single VLAN Mode (SVM) this should be
ICE_VLAN_OL_HW = 17.
Change protocol id in type to id translation array for outer vlan
to 17 when DVM is enabled, which means the driver, package,
and firmware support DVM.
