Subject: net: core: dev: replace state xoff flag comparison by
 netif_xmit_stopped method
Patch-mainline: v5.5-rc1
Git-commit: 5be5515a8ea198de6eb204a0ff25faf98b8ff719
References: bsc#1154353

Function netif_schedule_queue() has a hardcoded comparison between queue
state and any xoff flag. This comparison does the same thing as method
netif_xmit_stopped(). In terms of code clarity, it is better. See other
methods like: generic_xdp_tx() and dev_direct_xmit().
