Ard Biesheuvel 00425bb181 crypto: x86/sha512_ssse3 - fixup for asm function prototype change 
Patch e68410ebf6 ("crypto: x86/sha512_ssse3 - move SHA-384/512
SSSE3 implementation to base layer") changed the prototypes of the
core asm SHA-512 implementations so that they are compatible with
the prototype used by the base layer.

However, in one instance, the register that was used for passing the
input buffer was reused as a scratch register later on in the code,
and since the input buffer param changed places with the digest param
-which needs to be written back before the function returns- this
resulted in the scratch register to be dereferenced in a memory write
operation, causing a GPF.

Fix this by changing the scratch register to use the same register as
the input buffer param again.

Fixes: e68410ebf6 ("crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3 implementation to base layer")
