nl80211: Fix regression in returning to AP mode after scan

Browse source 
Commit b1f625e0d8 extended
ap_scan_as_station to be able to distinguish between AP and P2P GO
iftypes. However, it did this in a way that completely lost the original
mode because drv->nlmode had already been replaced with the station
mode. Fix this by storing the correct old mode.
