qcacmn: Disable CAC timer in special vaps

Special vap on AR9887 (ap_monitor) is used as both monitor and
AP mode. During channel change on DFS channels, vap is not up till DFS
CAC timer completes and hence cfg80211tool is not releasing the
rtnl_lock.
For Scan radio, CAC timer can be disabled on DFS channels.
