staging: ccree: fix buffer copy
Fix a bug where the copying of scatterlist buffers incorrectly
ignored bytes to skip in a scatterlist and ended 1 byte short.
This fixes testmgr hmac and hash test failures currently obscured
by hash import/export not being supported.
Fixes: abefd6741d ("staging: ccree: introduce CryptoCell HW driver").
