Missing '99.99' latency percentile

[mmichal10]

When printing trace statistics (iotrace -P -S -p <trace_path>), value of 99.900000th latency percentile is missing.
"latency": { "unit": "ns", "average": "8094", "min": "6851", "max": "5929010", "count": "262144", "total": "2121846323", "percentiles": { "90.000000th": 12288, "99.900000th": 6291456, "99.000000th": 24576 } }
Also notice that size percentiles are printed correct:
"size": { "unit": "sector", "average": "8", "min": "8", "max": "8", "count": "262144", "total": "2097152", "percentiles": { "99.000000th": 9.5, "90.000000th": 8.5, "99.900000th": 10.5, "99.990000th": 11.5 }
