crypto/sha256, crypto/sha512: fix argument size in assembly

The function takes 32 bytes of arguments: 8 for the *block
and then 3*8 for the slice.

The 24 is not causing a bug (today at least) because the
final word is the cap of the slice, which the assembly
does not use.

Identified by 'go vet std'.
