[PATCH] quieten zone_pcp_init

In zone_pcp_init we print out all zones even if they are empty:

On node 0 totalpages: 245760
  DMA zone: 245760 pages, LIFO batch:31
  DMA32 zone: 0 pages, LIFO batch:0
  Normal zone: 0 pages, LIFO batch:0
  HighMem zone: 0 pages, LIFO batch:0

To conserve dmesg space why not print only the non zero zones.
