media: i2c: og01a1b: Fix V4L2 subdevice data initialization on probe

It's necessary to finalize the camera sensor subdevice initialization on
driver probe and clean V4L2 subdevice data up on error paths and driver
removal.

The change fixes a previously reported by v4l2-compliance issue of
the failed VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT test:

  fail: v4l2-test-controls.cpp(1104): subscribe event for control 'User Controls' failed
