mm/vmstat.c: fix /proc/vmstat format for CONFIG_DEBUG_TLBFLUSH=y CONFIG_SMP=n

Browse Source 
commit e8277b3b52240ec1caad8e6df278863e4bf42eac upstream.

Commit 58bc4c34d249 ("mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly")
depends on skipping vmstat entries with empty name introduced in
7aaf77272358 ("mm: don't show nr_indirectly_reclaimable in
/proc/vmstat") but reverted in b29940c1abd7 ("mm: rename and change
semantics of nr_indirectly_reclaimable_bytes").

So skipping no longer works and /proc/vmstat has misformatted lines " 0".

This patch simply shows debug counters "nr_tlb_remote_*" for UP.
