can: usb_8dev: unregister netdev before free()ing

2013-07-03T17:55:37Z

commit 4afe2156eb639e563d6ef0c2706b66ea400348b2 upstream. The usb_8dev hardware has problems on some xhci USB hosts. The driver fails to read the firmware revision in the probe function. This leads to the following Oops: [ 3356.635912] kernel BUG at net/core/dev.c:5701! The driver tries to free the netdev, which has already been registered, without unregistering it. This patch fixes the problem by unregistering the netdev in the error path.
