qcacld-3.0: Add support for wakeable NLO_SCAN_COMPLETE_EVENT

Browse source 
This is a qcacld-2.0 to qcacld-3.0 propagation.

With RunTime PM feature enabled, after receiving the PNO matched event
RunTime PM puts the host back in WoW suspend after 500ms (default).
Since WMI_NLO_SCAN_COMPLETE_EVENTID is not a wakeable event, this event
does not wakeup the host hence PNO scan not completed and PNO is broken.

Fix this by making NLO_SCAN_COMPLETE_EVENT a wakeable event.
Host driver configures this WoW event only after PNO match is received.
