perfdata

i comment out line 156 and added the following line at 157, so all values can be used as perfdata:

strCheckOutputPerfData = “| used=”+str(intPoolUsageTB)+”TB; capacity=”+str(intPoolCapacityTB)+”TB; free=”+str(intPoolFreeSpaceTB)+”TB; CompRatio=”+str(fltPoolCompRatio)+”X; SavingRatio=”+str(fltPoolSavingsRatio)+”X”
