In free_pagetable() we use the non-atomic version for clearing the
PageReserved bit from the page.
free_pagetable() will either call free_reserved_page() or
put_page_bootmem(), which will eventually end up calling
free_serverd_page(), and in there we already clear the PageReserved flag.

This has been like this since commit ae9aae9eda2d ("memory-hotplug: common APIs to
support page tables hot-remove"), so I might be missing something obvious, but
I cannot explain why we would need that __ClearPageReserved upfront, when
free_reserved_pages() already does that for us.
Especially, we only call it on the first page (in case we'd have order>0).
