[PATCH] mm,page_owner: mark page_owner_threshold helpers as static

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The newly added functions have no prototype:

mm/page_owner.c:748:5: error: no previous prototype for 'page_owner_threshold_get' [-Werror=missing-prototypes]
mm/page_owner.c:754:5: error: no previous prototype for 'page_owner_threshold_set' [-Werror=missing-prototypes]

Evidently they are only meant to be used locally, so just mark them static.

Fixes: daed0e400a81 ("mm,page_owner: filter out stacks by a threshold counter")
