crypto: caam/qi2 - fix DMA mapping of stack memory
Commits c19650d6ea99 ("crypto: caam - fix DMA mapping of stack memory")
and 65055e210884 ("crypto: caam - fix hash context DMA unmap size")
fixed the ahash implementation in caam/jr driver such that req->result
is not DMA-mapped (since it's not guaranteed to be DMA-able).
Apply a similar fix for ahash implementation in caam/qi2 driver.
Cc: <stable@vger.kernel.org> # v4.20+
Fixes: 3f16f6c9d632 ("crypto: caam/qi2 - add support for ahash algorithms")
