IPACM: filter out AF_BRIDGE netlink message
In android platform, we observed the unexpected
dellink event is coming when usb-tethering is on
and enable wlan-AP hotspot next. Therefore IPACM
will think usb iface is down and clean up all the
rules on USB-RX pipe in IPA-HW. The fix is to
filter out these unexpected events which comes
with IP family: AF_BRIDGE.
