crypto: inside-secure - fix the extra cache computation
[ Upstream commit c1a8fa6e240ed4b99778d48ab790743565cb61c8 ]
This patch fixes the extra cache computation when the queued data is a
multiple of a block size. This fixes the hash support in some cases.
Fixes: 809778e02cd4 ("crypto: inside-secure - fix hash when length is a multiple of a block")
