    crypto: algif_hash - fix double free in hash_accept

    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: fe869cd ("crypto: algif_hash - User-space interface for hash operations")
