qcacld-3.0: Cleanup WOW_NLO_SCAN_COMPLETE_EVENT

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

Currently WOW_NLO_SCAN_COMPLETE_EVENT is enabled on receiving
PNO match found event, but it is never cleared.
This is causing regular host wake ups with the reason
WOW_REASON_NLO_SCAN_COMPLETE even if pno match is not found in the
next successive iterations.

Fix this by enabling/disabling WOW_NLO_SCAN_COMPLETE_EVENT before suspend
based on the flag pno match is found.
