Revert "mac80211: allow disable power save in mesh"
commit 2d3db210860f1df099a35b1dd54cca35454e0361 upstream.
This reverts commit ee1f668136b2fb6640ee2d54c2a525ea41f98211.
The aformentioned commit added a check to allow
'iw wlan0 set power_save off' to work for mesh interfaces.
However, this is problematic because it also allows
'iw wlan0 set power_save on', which will crash in short order
because all of the subsequent code manipulates sdata->u.mgd.
The power-saving states for mesh interfaces can be manipulated
through the mesh config, e.g:
'iw wlan0 set mesh_param mesh_power_save=active' (which,
despite the name, actualy disables power saving since the
setting refers to the type of sleep the interface undergoes).
