qcacld-2.0: Set burst duration when using short BI
When the DUT connects to an AP whose BI is short, for
example 25ms. Per the fw scan schedule mechanism, the
TBTT scan has high priority. Then the scan issued by
host will be timeout.
To mitigate this issue, enable the burst scan feature
by setting the burst scan duration.
