qcacld-3.0: Restart SAP if current channel is disabled

Currently when host receives disable channels command, it
disables the channels and if SAP is on it checks if SAP is
on one of the disabled channels in that case host stops the
SAP.
Based on current requirement host should restart the SAP,
with this change add support to restart the SAP if it is
operating on disabled channel.
