pagemap: fix large pages in pagemap
We were walking right into huge page areas in the pagemap walker, and
calling the pmds pmd_bad() and clearing them.
That leaked huge pages. Bad.
This patch at least works around that for now. It ignores huge pages in
the pagemap walker for the time being, and won't leak those pages.
