Subject: [PATCH v2] net: core: dev: replace state xoff flag comparison by netif_xmit_stopped method

From: Julio Faracco <jcfaracco@...il.com>

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().
