smaps: fix wrong rss count
A long time ago we regarded zero page as file_rss and vm_normal_page
doesn't return NULL.
But now, we reinstated ZERO_PAGE and vm_normal_page's implementation can
return NULL in case of zero page. Also we don't count it with file_rss
any more.
Then, RSS and PSS can't be matched. For consistency, Let's ignore zero
page in smaps_pte_range.
