[PATCH 02/28] media: ti-vpe: cal: fix error handling in cal_camerarx_create

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

cal_camerarx_create() doesn't handle error returned from
cal_camerarx_sd_init_cfg() and it always runs all the cleanup/free
functions in the error code path. The latter doesn't cause any issues at
the moment as media_entity_cleanup() is an empty function.

Fix the error handling.
