In ravb_probe, priv->work was bound with ravb_tx_timeout_work.
If timeout occurs, it will start the work. And if we call
ravb_remove without finishing the work, there may be a
use-after-free bug on ndev.

Fix it by finishing the job before cleanup in ravb_remove.

Note that this bug is found by static analysis, it might be
false positive.
