/proc/pid/maps: don't show pgoff of pure ANON VMAs
Recently, it's argued that what proc/pid/maps shows is ugly when a 32bit
binary runs on 64bit host.
/proc/pid/maps outputs vma's pgoff member but vma->pgoff is of no use
information is the vma is for ANON. With this patch, /proc/pid/maps shows
just 0 if no file backing store.
