> The device watchdog polls VFGEN_RSTAT to detect a VF reset and drives
> the auto-reset recovery path.
> It is disabled when a link-up event arrives, on the assumption that a
> working link means no reset is in flight.
> That assumption does not hold during recovery.
>
> Keep the watchdog armed while vf->in_reset_recovery is set, and enable
> it on VIRTCHNL_EVENT_RESET_IMPENDING, so it stays armed from the PF
> reset notification until recovery completes.
