[virt-tools-list] [virt-manager PATCH] serialcon: Close the console at the end of the stream

[Martin Kletzander]

When LXC guest was shut down while its console was open, virt-manager
got stuck in a loop due to the fact that the readable event was not
properly removed from the callback.  Mimicking the behavior from
libvirt's tolls/console.c file, this patch properly closes the console
in case stream.recv() returns empty string.
