[media] em28xx-camera: fix return value checks on sensor probing

Browse Source 
Since commit e63b009d6e the returned error code in case of not connected/responding
i2c clients is ENXIO isntead of ENODEV, which causes several error messages on
sensor probing.
Fix the i2c return value checks on sensor probing to silence these warnings.
