qcacld-3.0: Do not change home channel when update phymode from SON

瀏覽代碼 
When updating the phymode of SAP required from SON, do not change current
home channel. Currently hdd_restart_sap uses the channel information
from sap_config to do SAP restart. For SON, we need override the
sap_config channel information with desired channel information in vdev.
