[PATCH] qemu_process: show shutoff reasons when debug log disabled

[Chen Hanxiao <chen_han_xiao@xxxxxxx>]

From: Chen Hanxiao <chenhanxiao@xxxxxxxxx>

We have a few of senarios that libvirtd would invoke qemuProcessStop
and leave a "shutting down" in /var/log/libvirt/qemu/$DOMAIN.log.

The shutoff reason showing in debug log is also very important
for us to know why VM shutting down in domain log,
as we seldom enable debug log of libvirtd.
