Subject: [PATCH AUTOSEL 4.19 76/81] mlxsw: core: Do not use WQ_MEM_RECLAIM for mlxsw workqueue

From: Ido Schimmel <idosch@...lanox.com>

[ Upstream commit b442fed1b724af0de087912a5718ddde1b87acbb ]

The workqueue is used to periodically update the networking stack about
activity / statistics of various objects such as neighbours and TC
actions.

It should not be called as part of memory reclaim path, so remove the
WQ_MEM_RECLAIM flag.

Fixes: 3d5479e92087 ("mlxsw: core: Remove deprecated create_workqueue")
