Applied.

Note that we have a few spots now that do two synchronize_net()'s per
opertaion, such as team port removal, and openvswitch has such a path
as well.  They all are of the form:

	netdev_rx_handler_unregister()
	...
	lots of other stuff
	...
	synchronize_net();

So might be harder to factor back out than this br_if.c case.
