[PATCH net-next 1/3] mlxsw: Convert to async version of ndo_set_rx_mode

[Ido Schimmel <idosch@nvidia.com>]

Commit c5b9b518adab ("mlxsw: spectrum: Add set_rx_mode ndo stub") added
a stub for ndo_set_rx_mode to prevent dev_ifsioc() from returning an
error for the SIOCADDMULTI and SIOCDELMULTI cases.

Since then dev_ifsioc() was taught to also accept ndo_set_rx_mode_async
and commit 3cbd22938877 ("net: warn ops-locked drivers still using
ndo_set_rx_mode") modified register_netdevice() to warn when registering
an ops-locked net device that still uses ndo_set_rx_mode instead of
ndo_set_rx_mode_async.

In preparation for converting the driver to be ops-locked, convert the
ndo_set_rx_mode stub to a ndo_set_rx_mode_async stub.
