qlcnic: Enhance PVID handling for 84xx adapters
o PF driver should not indicate PVID configuration to VF driver.
As adapter supports VLAN stripping, VF driver should stay agnostic
to any PVID configuration.
o Return "QLC_NO_VLAN_MODE(= 0)" to VFD when PVID is configured.
VF driver should be in no VLAN configuration mode.
