crypto: inside-secure - fix hash when length is a multiple of a block
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).
