qcacld-3.0: Update RSO state on drv cmd for roam state
User uses SETROAMMODE command to enable/disable Legacy Fast Roaming.
Host processes SETROAMMODE and sets ini config value as per user
request and doesn't update RSO state in driver and doesn't update
RSO state change to FW. Due to this, runtime LFR config doesn't
take effect in FW and host RSO state machine.
Hence update RSO state in host and FW while processing SETROAMMODE
command.
