Fix abnormal wifi deactivationsubmit/tizen_3.0.m2/20170109.044454tizen_3.0.m2

The scan done event for SSID based scan was blocked to prevent Double Scan Indication Event
but It can cause abnormal wifi deactivation because the scanning flag may not be cleared correctly.
So the existing solution is removed and applied other solution.
