qcacld-3.0: Fix SAP close issue in dual band SAP

Browse source 
In Dual band SAP+SAP, if channel change for a SAP, the SAP get
stuck in eSAP_DISCONNECTING state, waiting for channel change
indication for the concurrent SAP, which may never come as this
is Dual band SAP+SAP and both are on different bands.

Now when stop adapter is called for this SAP, the stop BSS fails
as its already in disconnecting state and due to this it is not
deleted cleanly.

To fix this if DBS is enabled change the channel of the AP on
which CSA was initiated without waiting for other SAP interface.
