qcacld-3.0: Wait for sme_soc_set_dual_mac_config to get complete

SAP turn on is getting stuck for longer time due to vdev is getting
deleted logically before response for sme_soc_set_dual_mac_config comes.

To resolve this, add wait in wlan_hdd_update_dbs_scan_and_fw_mode_config
to confirm sme_soc_set_dual_mac_config completion.
