I'm not sure what this is trying to achieve.. As far as the claim about
WNM not being needed for MBO is concerned, the Wi-Fi Agile Multiband
specification mandate STA to support WNM-Notification Request frame.

And as far as adding CONFIG_WNM in mbo.c is concerned, this would have
no impact since this file is included only if CONFIG_MBO=y is defined
and if CONFIG_MBO is defined, then so will CONFIG_WNM.
