crypto: inside-secure - fix hash when length is a multiple of a block
commit 809778e02cd45d0625439fee67688f655627bb3c upstream.
This patch fixes the hash support in the SafeXcel driver when the update
size is a multiple of a block size, and when a final call is made just
after with a size of 0. In such cases the driver should cache the last
block from the update to avoid handling 0 length data on the final call
(that's a hardware limitation).
