qcacld-3.0: Don't skip RSO stop command if roaming is enabled

Currently, roaming state machine relies on the disconnect
sequence where link vdev gets disconnected first and then
assoc vdev. RSO stop is sent as part of link disconnection
and skipped for assoc vdev disconnection as the roaming
state machine is per ML than per link.
If link vdev connection hasn't happened due to some
reason (e.g. link not available in scan while connect, single link
ML connection), RSO stop command is not sent to firmware due
dependency on above sequence.
Check roam state while processing assoc vdev disconnect and send
RSO stop command to firmware if it's in enabled state to cleanup
the RSO state machine in firmware.
