crypto: ux500 - Fix error return code in hash_hw_final()
[ Upstream commit b01360384009ab066940b45f34880991ea7ccbfb ]
Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.
Fixes: 8a63b1994c50 ("crypto: ux500 - Add driver for HASH hardware")
