Re: [libvirt] [PATCH] util: Quiet the logging if perf file doesn't exist

Commit id 'b00d7f29' shifted the opening of the /sys/devices/intel_cqm/type file from event enable to perf event initialization. If the file did not exist, then an error would be written to the domain log: 2016-09-06 20:51:21.677+0000: 7310: error : virFileReadAll:1360 : Failed to open file '/sys/devices/intel_cqm/type': No such file or directory Since the error is now handled in virPerfEventEnable by checking if the event_attr->attrType == 0 for CMT, MBML, and MBMT events - we can just use the Quiet API in order to not log the error we're going to throw away. Additionally, rather than using virReportSystemError, use virReportError and VIR_ERR_ARGUMENT_UNSUPPORTED in order to signify that support isn't there for that type of perf event - adjust the error message as well.
