xfrm: Fix xfrm_policy_gc_lock handling.
From: Alexey Dobriyan <adobriyan@gmail.com> Based upon a lockdep trace by Simon Arlott. xfrm_policy_kill() can be called from both BH and non-BH contexts, so we have to grab xfrm_policy_gc_lock with BH disabling. Signed-off-by: David S. Miller <davem@davemloft.net>
