xen/setup: Only print "Freeing XXX-YYY pfn range: Z pages freed" if Z > 0
Otherwise we can get these meaningless: Freeing bad80-badf4 pfn range: 0 pages freed We also can do this for the summary ones - no point of printing "Set 0 page(s) to 1-1 mapping" Acked-by: David Vrabel <david.vrabel@citrix.com> [v1: Extended to the summary printks] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
