crypto: hash - Fix handling of small unaligned buffers
If a scatterwalk chain contains an entry with an unaligned offset then
hash_walk_next() will cut off the next step at the next alignment point.
However, if the entry ends before the next alignment point then we a loop,
which leads to a kernel oops.
Fix this by checking whether the next aligment point is before the end of the
current entry.
