swiotlb: ensure that page-sized mappings are page-aligned [ Upstream commit 602d9858f07c72eab64f5f00e2fae55f9902cfbe ] Some drivers do depend on page mappings to be page aligned. Swiotlb already enforces such alignment for mappings greater than page, extend that to page-sized mappings as well. Without this fix, nvme hits BUG() in nvme_setup_prps(), because that routine assumes page-aligned mappings.
