selftests/mm: uffd-unit-tests support for hugepages > 2M
uffd-unit-tests uses a memory area with a fixed 32M size. Then it
calculates the number of pages by dividing by page_size, which itself is
either the base page size or the PMD huge page size depending on the test
config. For the latter, we end up with nr_pages=1 for arm64 16K base
pages, and nr_pages=0 for 64K base pages. This doesn't end well.
So let's make the 32M size a floor and also ensure that we have at least 2
pages given the PMD size. With this change, the tests pass on arm64 64K
base page size configuration.
