xfrm: don't skip free of empty state in acquire policy
[ Upstream commitf3ec2b5d87
] In destruction flow, the assignment of NULL to xso->dev caused to skip of xfrm_dev_state_free() call, which was called in xfrm_state_put(to_put) routine. Instead of open-coded variant of xfrm_dev_state_delete() and xfrm_dev_state_free(), let's use them directly. Fixes:f8a70afafc
