media: ov5640: fix spurious streamon failures
Time to time, stream on is failing with a strange positive error. Error code is returned erroneously by ov5640_set_ctrl_exposure() due to ov5640_get_vts() return value wrongly treated as error. Fix this by forcing ret to 0 after ov5640_get_vts() success call, in order that ret is set to success for rest of code sequence.
