[libvirt] [PATCH] Don't overwrite errors raised by qemuMonitorHMPCommand

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The qemuMonitorHMPCommand() API and things it calls will report a wide variety of errors. The QEMU text monitor should not be overwriting these errors Signed-off-by: Daniel P.
