UPSTREAM: mm/slab: clean up DEBUG_PAGEALLOC processing code
Currently, open code for checking DEBUG_PAGEALLOC cache is spread to
some sites. It makes code unreadable and hard to change.
This patch cleans up this code. The following patch will change the
criteria for DEBUG_PAGEALLOC cache so this clean-up will help it, too.
