crypto: api - Fix race condition in crypto_spawn_alg
commit bc1d8cb6169a2deb7dbcad8ac6ed8ade1bc2bb05 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.
