qcacld-3.0: Fix RSO state change in disconnected state

When roaming has started and connect request from userspace
is received, disconnect is initiated as part of the connect
request and RSO stop->RSO Deinit is sent to firmware. But
before receiving the RSO stop, firmware posted the Roam Synch
indication to the host driver. While droping the roam
synch indication, the driver does abort roaming and as part of
that RSO state is changed to RSO enabled in connecting state.

Change the RSO state to RSO enabled only if roaming or roam synch
indication processing is in progress.
