mm, shmem: fix handling /sys/kernel/mm/transparent_hugepage/shmem_ena…
…bled commit 435c0b8 upstream. /sys/kernel/mm/transparent_hugepage/shmem_enabled controls if we want to allocate huge pages when allocate pages for private in-kernel shmem mount. Unfortunately, as Dan noticed, I've screwed it up and the only way to make kernel allocate huge page for the mount is to use "force" there. All other values will be effectively ignored.
