qcacld-3.0: Send RSO Start followed by RSO Stop for supplicant disabled roam

Currently, if supplicant disabled roaming, driver doesnot send RSO
cmd to fw. This causes roam invoke to fail in FW since RSO start
never happened at least once to configure roaming engine in FW.

After connection, Send RSO start followed by RSO Stop if supplicant
disabled roaming to make sure roaming engine in FW is configured
properly with required parameters at least once.
