[PATCH v5 3/4] media: renesas: rcar-core: Add missing media_entity_cleanup()

[Biren Pandya <birenpandya@gmail.com>]

The probe error path and remove function fail to call
media_entity_cleanup() upon teardown.

While currently a no-op, calling media_entity_cleanup()
is an API requirement for entities initialized with
media_entity_pads_init()
to prevent memory leaks.

Add a dedicated error_entity label so the cleanup is only invoked when
media_entity_pads_init() has actually succeeded. This ensures that the
teardown logic properly mirrors initialization.
