Luyao Huang 4f06820938 qemu: do not overwrite the error in qemuDomainObjExitMonitor 
https://bugzilla.redhat.com/show_bug.cgi?id=1196934

When qemu exits during startup, libvirt includes the error from
/var/log/libvirt/qemu/vm.log in the error message:

$ virsh start test3
error: Failed to start domain test3
error: internal error: early end of file from monitor: possible problem:
2015-02-27T03:03:16.985494Z qemu-kvm: -numa memdev is not supported by
machine rhel6.5.0

The check for domain liveness added to qemuDomainObjExitMonitor
in commit dc2fd51f sometimes overwrites this error:
$ virsh start test3
error: Failed to start domain test3
error: operation failed: domain is no longer running

Fix the check to only report an error if there is none set.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
