[PATCH AUTOSEL 4.14 90/95] mlxsw: core: Do not use WQ_MEM_RECLAIM for EMAD workqueue

[Sasha Levin]

From: Ido Schimmel <idosch@xxxxxxxxxxxx>

[ Upstream commit a8c133b06183c529c51cd0d54eb57d6b7078370c ]

The EMAD workqueue is used to handle retransmission of EMAD packets that
contain configuration data for the device's firmware.

Given the workers need to allocate these packets and that the code is
not called as part of memory reclaim path, remove the WQ_MEM_RECLAIM
flag.
