i40e: Invoke softirqs after napi_reschedule
The following message is logged from time to time when using i40e:
NOHZ: local_softirq_pending 08
i40e may schedule napi from a workqueue. Afterwards, softirqs are not run
in a deterministic time frame. The problem is the same as what was
described in commit ec13ee80145c ("virtio_net: invoke softirqs after
__napi_schedule") and this patch applies the same fix to i40e.
