Subject: [PATCH 3/7] crypto: stm32 - remove bufcnt in stm32_hash_write_ctrl.

From: Thomas Bourgoin <thomas.bourgoin@...s.st.com>

Commit "crypto: stm32 - Fix empty message processing" remove the use of
the argument bufcnt in stm32_hash_write_ctrl.
Hence, we can remove it from the function prototype and simplify the
function declaration.
