qcacld-3.0: Send Roam scan mode value 0 to disable roaming

When RSO stop is sent to firmware, if reason is disconnect
or driver internally disabled roam, the Roam scan mode should
be 0, but driver is sending value as 4. This causes firmware
to have roam offload registered on 2 vdevs for targets where
simultaneous roaming is not enabled.

Pass the proper reason code to fill roam scan mode config
while sending RSO stop.
