qcacld-3.0: Fix roam failed for SAP CSA concurrency
When vdev0 STA roamed to another channel, vdev1 SAP CSA for SCC
when ROAM_SYNCH_IN_PROG, will disable roam, but no RSO stop to F/W,
F/W RSO isn't disabled, but host vdev0 will enter RSO_STOPPED, host
F/W RSO state out of sync.
If vdev0 STA next roam sync come soon, it won't be handled for host
RSO_STOPPED, neither roam sync complete nor disconnect will happen,
F/W will asert after wait roam sync complete timeout.
To fix it, Only do SAP CSA check after roam complete and RSO
reenabled, can avoid host F/W RSO state out of sync issue.
