In kmalloc_oob_krealloc_less, I think it is better to test
the size2 boundary.
If we do not call krealloc, the access of position size1 will
still cause out-of-bounds and access of position size2 does not.
After call krealloc, the access of position size2 cause
out-of-bounds. So, use size2 is more correctly.
