[PATCH 04/22] media: i2c: mt9v011: Add missing media_entity_cleanup()

[Biren Pandya <birenpandya@gmail.com>]

The media_entity_pads_init() function initializes the media entity, but
the driver forgets to call media_entity_cleanup() in the error paths
and remove function. Add the missing calls to fix the API violation and
prevent potential future memory leaks.
