g_regex_unref reports an error if called with a NULL argument.
We have two cases in the code where we (possibly) call it on a NULL
argument. The interesting one is in virDomainQemuMonitorEventCleanup.
Based on VIR_CONNECT_DOMAIN_QEMU_MONITOR_EVENT_REGISTER_REGEX, we unref
data->regex, which has two problems:
* On the client side, flags is -1 so the comparison is true even if no
regex was used, reproducible by:
$ virsh qemu-monitor-event --timeout 1
which results in an ugly error:
(process:1289846): GLib-CRITICAL **: 14:58:42.631: g_regex_unref: assertion 'regex != NULL' failed
* On the server side, we only create the regex if both the flag and the
string are present, so it's possible to trigger this message by:
$ virsh qemu-monitor-event --regex --timeout 1
Use a non-NULL comparison instead of the flag to decide whether we need
to unref the regex. And add a non-NULL check to the unref in the
VirtualBox test too.
