If a device reported an empty processor load in the HOST-RESOURCES-MIB (hrProcessorLoad) for one of its processors, the CPU utilization service crashed with ValueError: invalid literal for int() with base 10: ''.

The service now goes to UNKNOWN and names the processor whose load could not be read, together with the value received. The utilization of the remaining processors is still reported.
