libvirt unrescue doesn't cleanup rescue images

[Dan Prince]

Looks like we are leaving the .unrescue files around after performing an unrescue operation.

After performing an unrescue (the instance goes back to ACTIVE) this is what I see:

[root@nova1 nova]# nova list
+--------------------------------------+------+--------+--------------------+
| ID | Name | Status | Networks |
+--------------------------------------+------+--------+--------------------+
| cb2b759c-7d2e-430d-8de4-89382dbe9c40 | test | ACTIVE | public=192.168.0.2 |
+--------------------------------------+------+--------+--------------------+

[root@nova1 nova]# ls /var/lib/nova/instances/instance-00000008/
console.log disk.rescue kernel.rescue libvirt.xml.rescue ramdisk.rescue
disk kernel libvirt.xml ramdisk
