Re: [libvirt] [PATCH 6/6] qemu: Resolve Coverity RESOURCE_LEAK

This seemed to be more of a false positive as for some reason Coverity was missing the "ret < 0" goto error condition and somehow believing that event could be overwritten. At first I thought it was just the ret != 0 condition difference, but it wasn't.

In any case, make use of the recent change to qemuDomainEventQueue to check event == NULL and just pass it as a parameter directly in the error path. That avoids the error.
