Rik van Riel cd89fb0650 mm,thp,shmem: make khugepaged obey tmpfs mount flags
Currently if thp enabled=[madvise], mounting a tmpfs filesystem with
huge=always and mmapping files from that tmpfs does not result in
khugepaged collapsing those mappings, despite the mount flag indicating
that it should.

Fix that by breaking up the blocks of tests in hugepage_vma_check a little
bit, and testing things in the correct order.
