mm/page_owner.c: modify the type of argument "order" in some functions
The type of "order" in struct page_owner is unsigned short.
However, it is unsigned int in the following 3 functions:
__reset_page_owner
__set_page_owner_handle
__set_page_owner_handle
The type of "order" in argument list is unsigned int, which is
inconsistent.
