Subject: crypto: cryptd - initialize child shash_desc on import
From: Ard Biesheuvel <ard.biesheuvel@xxxxxxxxxx>
commit 0bd2223594a4dcddc1e34b15774a3a4776f7749e upstream.
When calling .import() on a cryptd ahash_request, the structure members
that describe the child transform in the shash_desc need to be initialized
like they are when calling .init()
