media: uvcvideo: Fix support for V4L2_CTRL_FLAG_HAS_WHICH_MIN_MAX

The VIDIOC_G_EXT_CTRLS with which V4L2_CTRL_WHICH_(MIN|MAX)_VAL can only
work for controls that have previously announced support for it.

This patch fixes the following v4l2-compliance error:

  info: checking extended control 'User Controls' (0x00980001)
  fail: v4l2-test-controls.cpp(980): ret != EINVAL (got 13)
        test VIDIOC_G/S/TRY_EXT_CTRLS: FAIL
