octeon_ep: cancel tx_timeout_task later in remove sequence

[ Upstream commit 28458c8000 ]

tx_timeout_task is canceled too early when removing the driver. Nothing
prevents .ndo_tx_timeout from triggering and queuing the work again.

Better cancel it after the netdev is unregistered.
It's harmless for octep_tx_timeout_task to run in the window between the
unregistration and cancelation, because it checks netif_running.
