qcacld-3.0: Modify the active dwell time in scan for ssid

Currently the driver scans for the bssid if it is not present
in the scan cache, due to expire of scan results.
But the active dwell time set in the scan request is Zero,
hence the active probe is not sent to the AP, and the DUT
(STA in this case), just passively scans the channels for that
BSSID, which causes latency in connection.

Fix is to initialize the default active dwell time in case of
scan for ssid.
