Need to cleanup bridge device timers and ports when being bridge
device is being removed via netlink.
This fixes the problem of observed when doing:
ip link add br0 type bridge
ip link set dev eth1 master br0
ip link set br0 up
ip link del br0
which would cause br0 to hang in unregister_netdev because
of leftover reference count.
