Subject: [PATCH 01/16] can: usb_8dev: Fix memory leak in usb_8dev_start_xmit

From: Bjorn Van Tilt <bjorn.vantilt@...il.com>

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.
