[EXT] [PATCH] crypto/qat: fix raw API null algorithm digest

[Akhil Goyal]

> QAT HW generates bytes of 0x00 digest, even when a digest of len 0 is
> requested for NULL. This caused test failures when the test vector had
> digest len 0, as the buffer has unexpected changed bytes.
> 
> By placing the digest into the cookie for NULL authentication,
> the buffer remains unchanged as expected, and the digest
> is placed to the side, as it won't be used anyway.
> 
> This fix was previously added for the main QAT code path, but it also
> needs to be included for the raw API code path.
