crypto: ahash - Fix early termination in hash walk

Browse source

commit 900a081f69 upstream.

When we have an unaligned SG list entry where there is no leftover
aligned data, the hash walk code will incorrectly return zero as if
the entire SG list has been processed.

This patch fixes it by moving onto the next page instead.
