qcacld-3.0: Change INDOOR channel check to PASSIVE channels

Browse Source 
INDOOR channels may or may not be enabled for SAP. If
INDOOR channels are not enabled for SAP, they are converted
to PASSIVE channels. So remove PASSIVE channels from SAP
channel list. Also remove any function not getting called
any more.
