[ Upstream commit 602649eadaa0c977e362e641f51ec306bc1d365d ]

In case of errors vpif_probe_complete() releases memory for vpif_obj.sd
and unregisters the V4L2 device. But then this is done again by
vpif_probe() itself. The patch removes the cleaning from
vpif_probe_complete().

Found by Linux Driver Verification project (linuxtesting.org).
