Fix 2 sub issues:
1. wlan_hdd_update_dbs_scan_and_fw_mode_config and
sme_soc_set_dual_mac_config is called in
hdd_wlan_start_modules->hdd_configure_cds->hdd_features_init,
before hdd_start_adapter, so vdev isn't created yet,
csr_queue_sme_command returned failed
Fixed by moving wlan_hdd_update_dbs_scan_and_fw_mode_config to
end of hdd_start_adapter
2. Rome doesn't support DBS, doesn't support cmd and wmi service
WMI_PDEV_SET_MAC_CONFIG_CMDID. so no response event for the cmd,
the cmd can't be removed from active list. so next cmd:
WMA_ADD_STA_SELF_REQ can't be executed at all, no complete event
for sme_open_session, hdd_init_station_mode failed
Fixed by checking whether support HW DBS before
sme_soc_set_dual_mac_config
