mm/page_alloc: remove unnecessary __maybe_unused in order_to_pindex()
The `movable` variable is always used when `CONFIG_TRANSPARENT_HUGEPAGE`
is enabled, so the `__maybe_unused` attribute is not necessary. This
patch removes it and keeps the variable declaration within the `#ifdef`
block for better clarity.
