crypto: af_alg - Use bh_lock_sock in sk_destruct
commit 37f96694cf73ba116993a9d2d99ad6a75fa7fdb0 upstream.
As af_alg_release_parent may be called from BH context (most notably
due to an async request that only completes after socket closure,
or as reported here because of an RCU-delayed sk_destruct call), we
must use bh_lock_sock instead of lock_sock.
