[libvirt] [PATCH 2/2] qemu: snapshot: Forbid snapshots of iSCSI passthrough devices

As with the local SCSI passthrough devicesm qemu can't support snapshots on those as the block ops are handled by the device. This is also true for iSCSI backing of the disk. Remove the check for the local block device and just forbid snapshot when the disk is of type 'lun'.
