Subject: [net-next PATCH v2 4/4] netdev: use napi_schedule bool instead of napi_schedule_prep/__napi_schedule

From: Christian Marangi <[email-masked]>
Date: Tue, 3 Oct 2023 16:51:50 +0200

Replace if condition of napi_schedule_prep/__napi_schedule and use bool
from napi_schedule directly where possible.
