Subject: [PATCH 22/28] ocelot: Cancel delayed work before wq destruction

From: Claudiu Manoil <[email-masked]>
Date: Thu, 25 Jul 2019 16:33:18 +0300

[ Upstream commit c5d139697d5d9ecf9c7cd92d7d7838a173508900 ]

Make sure the delayed work for stats update is not pending before
wq destruction.
This fixes the module unload path.
The issue is there since day 1.

Fixes: a556c76adc05 ("net: mscc: Add initial Ocelot switch support")
