mm: don't show nr_indirectly_reclaimable in /proc/vmstat 

commit 7aaf772723 upstream.

Don't show nr_indirectly_reclaimable in /proc/vmstat, because there is
no need to export this vm counter to userspace, and some changes are
expected in reclaimable object accounting, which can alter this counter.
