qcacld-3.0: Clear Static channel list in fw for SETROAMSCANCONTROL 0

Browse Source 
In the present implementation, it is observed that "SETROAMSCANCONTROL 0"
command is not clearing STATIC channels in the firmware for ROAM scan list.

So to clear STATIC channels configured for ROAM scan and set dynamically
added ROAM scan channels host sends two RSO commands to Firmware.

In the first RSO command STATIC channel list is cleared and second RSO
command will add dynamically added ROAM scan channels to ROAM scan list
in firmware.
