From: Leon Romanovsky <leonro@xxxxxxxxxx>
Mulitport slave device doesn't support devlink reload, so instead of
complicating initialization flow with devlink_reload_enable() which
will be removed in next patch, set specialized devlink ops callbacks
for reload operations.
This fixes an error when reload counters exposed (and equal zero) for
the mode that is not supported at all.
Fixes: d89ddaae1766 ("net/mlx5: Disable devlink reload for multi port slave device")
