can: usb_8dev: Fix memory leak in usb_8dev_start_xmit
Fixed a memory leak when an error occurred in the transmit function. In the error handling the urb wasn't freed before returning. There was also a call to the usb_unanchor_urb() function but the urb wasn't anchored. Signed-off-by: Bjorn Van Tilt <bjorn.vantilt@gmail.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
