[PATCH net 3/4] octeon_ep: cancel ctrl_mbox_task after intr_poll_task

[Michal Schmidt <mschmidt@redhat.com>]

intr_poll_task may queue ctrl_mbox_task. The function
octep_poll_non_ioq_interrupts_cn93_pf does this.

When removing the driver and canceling these two works, cancel
ctrl_mbox_task last to guarantee it does not run anymore.

Fixes: 24d4333233b3 ("octeon_ep: poll for control messages")
