mm/page_alloc: Fix try_alloc_pages

Fix an obvious bug. try_alloc_pages() should set_page_refcounted.

[ Not so obvious: it was probably correct at the time it was written but
  was at some point then rebased on top of v6.14-rc1.

  And at that point there was a semantic conflict with commit
  efabfe14 ("mm/page_alloc: move set_page_refcounted() to callers
  of get_page_from_freelist()") and became buggy.
							- Linus ]
