Below is the sequence of events causing RSO init command to
be sent to firmware while disconnect is happening:
1. Roam Start received from firmware in scheduler thread.
2. Connect request for reassoc received in supplicant thread.
3. This connect request triggers disconnect, but before RSO stop
& deinit is sent to firmware, roam synch event is received. This
roam synch is getting processed in the scheduler thread. But RSO
stop & deinit are sent in wpa_supplicant thread.
4. As part of roam synch host is posting RSO_ENABLE to RSO state
machine which triggers roam init to firmware.
5. Since disconnect sequence is already in progress, the RSO is
in init state before vdev stop. Disconnect sequence got executed
cleanly except for the RSO sequence.
This results in abnormal firmware behavior.
Check if the vdev is in connected state before sending roam init
to firmware.
