mm: shmem: move shmem_huge_global_enabled() into shmem_allowable_huge_orders()

Browse source

Move shmem_huge_global_enabled() into shmem_allowable_huge_orders(), so
that shmem_allowable_huge_orders() can also help to find the allowable
huge orders for tmpfs.  Moreover the shmem_huge_global_enabled() can
become static.  While we are at it, passing the vma instead of mm for
shmem_huge_global_enabled() makes code cleaner.

No functional changes.
