Roman Gushchin c29f9010a3 mm: hide incomplete nr_indirectly_reclaimable in /proc/zoneinfo 
[fixed differently upstream, this is a work-around to resolve it for 4.14.y]

Yongqin reported that /proc/zoneinfo format is broken in 4.14
due to commit 7aaf772723 ("mm: don't show nr_indirectly_reclaimable
in /proc/vmstat")

The problem is caused by the nr_indirectly_reclaimable counter,
which is hidden from the /proc/vmstat, but not from the
/proc/zoneinfo. Let's fix this inconsistency and hide the
counter from /proc/zoneinfo exactly as from /proc/vmstat.

BTW, in 4.19+ the counter has been renamed and exported by
the commit b29940c1ab ("mm: rename and change semantics of
nr_indirectly_reclaimable_bytes"), so there is no such a problem
anymore.
