[PATCH v3 1/3] media: i2c: ov8856: free control handler on error in ov8856_init_controls()

[Alexander Koskovich]

The control handler wasn't freed if adding controls failed, add an error
exit label and convert the existing error return to use it.

Fixes: 879347f0c258 ("media: ov8856: Add support for OV8856 sensor")
