crypto: api - Fix races in crypto_unregister_instance There are multiple problems in crypto_unregister_instance: 1) The cra_refcnt BUG_ON check is racy and can cause crashes. 2) The cra_refcnt check shouldn't exist at all. 3) There is no reference on tmpl to protect the tmpl->free call. This patch rewrites the function using crypto_remove_spawn which now morphs into crypto_remove_instance. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
