RFR: 8208676: Consistent crash when getting event on NetworkPerformanceInterface::NetworkPerformance::network_utilization

[Robin Westberg]

Hi Markus,

Thanks for reviewing!

When reading the getifaddrs documentation I noticed another mistake which I think would be nice to fix at the same time (missing call to freeifaddrs).

New webrev: http://cr.openjdk.java.net/~rwestberg/8208676/webrev.01/ <http://cr.openjdk.java.net/~rwestberg/8208676/webrev.01/>
Testing: jdk.jfr.event.runtime.* on linux-x64, linux-x64-debug, solaris-sparcv9, solaris-sparcv9-debug

Best regards,
Robin
