[libvirt] [PATCH] util: Fix memory leak in virResctrlMonitorGetStats

[John Ferlan]

Missed during review and surprisingly my run through Coverity also
didn't see this. I only noticed it when reading the code while fixing
the build breaker for commit 36780a86a.

With all those continues we would leak @stats.
