qcacld-3.0: Update Set Roam Primary reason in the roam stop config

Currently, roam scan mode is updated as roam offload while setting
primary vdev, but expected scan mode in this case is none. This is due
to wrong reason is propagated from cm_roam_stop_req to
cm_roam_scan_offload_fill_rso_configs.
So, reason in roam stop config is updated with set roam primary which is
propagated to cm_roam_scan_offload_fill_rso_configs.
