Subject: [PATCH] media: tvp5150: Add missed media_entity_cleanup()

This driver does not call media_entity_cleanup() in the error handler
of tvp5150_registered() and tvp5150_remove(), while it has called
media_entity_pads_init() at first.
Add the missed calls to fix it.

Fixes: 0556f1d580d4 ("media: tvp5150: add input source selection of_graph support")
