The uvc_set_ctrl() calls don't write to the hardware. A failure at that point thus leaves the device in a clean state, with no control modified. Set the error_idx field to the count value to reflect that, as per the V4L2 specification. TRY_EXT_CTRLS is unchanged and the error_idx field must always be set to the failed control index in that case.
