Host driver doesn't disable RSO before restarting the vdev
for fw-initiated as well host-initiated CSA or BW change for
link vdev. Therefore, if the FW is in middle of roam(for host
initiated CSA) cases, this restart leads to race condition in FW.
Add a new reason code for VDEV restarts triggered due to CSA,
enable/disable the RSO SM based on this new reason code for
assoc as well as partner links.
