crypto: api - Fix race condition in crypto_spawn_alg
commit 73669cc556462f4e50376538d77ee312142e8a8a upstream.
The function crypto_spawn_alg is racy because it drops the lock
before shooting the dying algorithm. The algorithm could disappear
altogether before we shoot it.
This patch fixes it by moving the shooting into the locked section.
