Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188551. A negative return value means there are errors, while 0 indicates success. However, in function bpa10x_send_frame(), it returns 0 no matter whether usb_submit_urb() returns a negative value. As a result, the caller of bpa10x_send_frame() may not detect the submission error. In this patch, use "return err;" at the end to propagate the error.
