drm/ttm: fix out-of-bounds read in ttm_put_pages() v2
commit a66477b0efe511d98dde3e4aaeb189790e6f0a39 upstream.
When ttm_put_pages() tries to figure out whether it's dealing with
transparent hugepages, it just reads past the bounds of the pages array
without a check.
v2: simplify the test if enough pages are left in the array (Christian).
