nl80211: Abort an ongoing scan upon scan timeout indication

Browse source 
Currently, when scan is stuck in the kernel/driver/fw,
the nl80211 driver tries to recover by faking a SCAN_RESULTS flow.
However, the scan is still stuck in the kernel/driver/fw.

To avoid that stuck request, abort it upon scan timeout.
