qcacld-3.0: Fix rate population on channel change of SAP

On channel change of SAP to 5G, SAP is populating 2.4G basic
rates in 5G beacon.

Set number of supported and extended rates to zero for populating
rates based on network type. CSR layer will pick default rates if
hostapd rates are passed as zero
