[libvirt] [v0.9.12-maint v2 11/12] Don't ignore return value of qemuProcessKill

From: "Daniel P. Berrange" <berrange redhat com>

When calling qemuProcessKill from the virDomainDestroy impl
in QEMU, do not ignore the return value. This ensures that
if QEMU fails to respond to SIGKILL, the caller will know
about the failure.
