qcacmn: Enable STA DFS in F/W

If STA DFS is enabled before vdev creation through etc/config/wireless
then VDEV START is sent to F/W as a part of the normal flow to bring
the VAP up. However, if STA DFS is enabled/disabled on the fly for a
running VAP then do a VDEV STOP, followed by a VDEV START of the STA
VAP and set/unset WMI_CHAN_FLAG_STA_DFS flag in VDEV start.
