[libvirt] [PATCH] virsh: Free stream when shutdown console

[Osier Yang]

Otherwise connection of hypervisor driver will be leaked when
one shutdown the guest in console. e.g.

[root at localhost]# init 0
......
init: Re-executing /sbin/init
Halting system...
Power down.

error: Failed to disconnect from the hypervisor, 1 leaked reference(s)
