bridge: Simplify pvid checks.
Currently, if the pvid is not set, we return an illegal vlan value even though the pvid value is set to 0. Since pvid of 0 is currently invalid, just return 0 instead. This makes the current and future checks simpler. Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
