    Clear correct device when deleting a ThinLVM snap

    The LVM driver tries to wipe a device using dd when
    a snapshot is deleted. For ThinLVM, it is attempting
    to wipe the /dev/mapper/cinder--volumes-<vol>-cow device,
    which does not exist for ThinLVM. This causes snapshot
    deletion to fail for ThinLVM if volume clearing is on.

    When using ThinLVM, only wipe the LV device rather than
    attempting to wipe the -cow device.

    This bug is only present in stable/grizzly (2013.1.4).
    It does not exist in stable/havana or master due to these
    changes:
    f702fe7 Fix secure delete for thick LVM snapshots
    de43923 Don't zero out thin provisioned LV's on delete
