crypto: hash - Fix handling of unaligned buffers
The correct way to calculate the start of the aligned part of an
unaligned buffer is:
offset = ALIGN(offset, alignmask + 1);
However, crypto_hash_walk_done() has:
offset += alignmask - 1;
offset = ALIGN(offset, alignmask + 1);
which actually skips a whole block unless offset % (alignmask + 1) == 1.
This patch fixes the problem.
