btrfs: use u64 for the page indices in heuristic_collect_sample()

index and index_end are derived from the u64 start and end offsets, and
index is shifted back into a byte offset for offset_in_folio(), which
needs a cast to u64 to be safe on 32-bit. Make them u64 instead so the
cast goes away. They still fit pgoff_t where they are passed to
filemap_get_folio(), as they came from a valid file offset.
