In the quest to remove all stack VLA usage from the kernel[1], this
removes the discouraged use of AHASH_REQUEST_ON_STACK by switching to
shash directly and allocating the descriptor in heap memory (which should
be fine: the tfm has already been allocated there too).

I think I can queue this up if there are no objections from others.

Do you want me to do that?

Sure thing. It looks like the other stand-alone patches like this one
are getting taken into the non-crypto trees, so that's fine.

Thanks!
