bridge: Apply the PVID to priority-tagged frames
bridge: Apply the PVID to priority-tagged frames

IEEE 802.1Q says that when we receive priority-tagged (VID 0) frames
use the PVID for the port as its VID.
(See IEEE 802.1Q-2011 6.9.1 and Table 9-2)

Apply the PVID to not only untagged frames but also priority-tagged frames.
