Ivan Pravdin 5bff312b59 crypto: algif_hash - fix double free in hash_accept 
commit b2df03ed40 upstream.

If accept(2) is called on socket type algif_hash with
MSG_MORE flag set and crypto_ahash_import fails,
sk2 is freed. However, it is also freed in af_alg_release,
leading to slab-use-after-free error.

Fixes: fe869cdb89 ("crypto: algif_hash - User-space interface for hash operations")
