qcacld-3.0: Fix LTE unsafe channel switching failure of SAP

Browse source 
At present LTE unsafe channel switch and DCS is using
hdd_switch_sap_channel to switch channel of SAP.
hdd_switch_sap_channel has no bw setting parameters and just
use the original bw of SAP - ch_width_orig. The ch_width_orig
(80Mhz) may not be applicable if SAP is channel switching from
5G 80Mhz to 2G. Use the new API wlan_get_ap_prefer_conc_ch_params
to override the bw to appropriate value for the new channel.
