The uffd VMA-flag helpers read vma->vm_flags directly. Now that config-gated per-mode masks exist, switch them to the vma_flags_t accessor vma_test_any_mask(), which is the going-forward API and keeps a single place (the VMA_UFFD_* masks) that knows which modes are available on the current build. No functional change: vma_flags_t is in union with vm_flags, so the same bits are read, and the masks fold to the same code the open-coded vm_flags tests produced -- verified identical on gcc and clang, 32- and 64-bit.
