Jianbo Liu bfbf576f29 bonding: implement xdo_dev_state_free and call it after deletion 
[ Upstream commit ec13009472 ]

Add this implementation for bonding, so hardware resources can be
freed from the active slave after xfrm state is deleted. The netdev
used to invoke xdo_dev_state_free callback, is saved in the xfrm state
(xs->xso.real_dev), which is also the bond's active slave. To prevent
it from being freed, acquire netdev reference before leaving RCU
read-side critical section, and release it after callback is done.

And call it when deleting all SAs from old active real interface while
switching current active slave.
