qcacld-3.0: Fix to restart SAP on preferred channel
qcacld-2.0 to qcacld-3.0 propagation
In some case when complete preferred channel list is unsafe,
SAP won't be able to pick any channel as operating channel.
This will lead to SAP start failure.
Fix this issue by making first channel from preferred channel
list as operating channel.
