Subject: [PATCH v2 2/6] crypto: stm32/hash: Simplify code

We are passing (rctx->flags & HASH_FLAGS_FINUP) as indicator
for the final request but we already know this to be true since
we are in the (final) arm of an if-statement set from the same
flag. Just open-code it as true.

Acked-by: Lionel Debieve <lionel.debieve@...s.st.com>
