[PATCH] media: i2c: rdacm21: Fix missing media_entity_cleanup()

[Biren Pandya]

If v4l2_async_register_subdev() fails, or if rdacm21_probe() hits any
other error after media_entity_pads_init() is called, the media entity
is left uncleaned, potentially leaking resources or leaving it in an
invalid state. Similarly, the remove path misses the cleanup.

Add media_entity_cleanup() to both the error path in rdacm21_probe() and
the rdacm21_remove() function to ensure proper resource release.

Fixes: a59f853b3b4b ("media: i2c: Add driver for RDACM21 camera module")
