[PATCH net 2/4] octeon_ep: cancel tx_timeout_task later in remove sequence

[Michal Schmidt <mschmidt@redhat.com>]

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.

Fixes: 862cd659a6fb ("octeon_ep: Add driver framework and device initialization")
