check_icmp: Fix pkt perfdata in check_host mode

Add missing "warn" threshold field in "pkt" perfdata output.
Perfdata should be interpreted as;

  'label'=value[UOM];[warn];[crit];[min];[max]

With one field missing, the hardcoded min value '0' ended up in the
"crit" field, making applications interpreting the perfdata thining that
critical threshold is always exceeded.
