Clang's static analyzer pointed out that if alloc_pages >= nr_pages before the loop, the value of page will be undefined and will be used anyway. This should not be possible, but as cleanup, we add an assertion. We also recognize that the local variables should be unsigned in the first place, so we make them unsigned. This is not enough to avoid the need for the assertion, since there is still the case that alloc_pages == nr_pages and nr_pages == 0, which the assertion implicitly checks.
