[media] uvcvideo: Set error_idx properly for S_EXT_CTRLS failures
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.
