wlan: Add ini parametr to configure dwell time for first time

Add ini parameter, gIntialDwellTime, to configure dwell time
for the first time. By updating this parameter, we are configuring
maxChnTime(max channel time).

By default this parameter is set to 0, meaning maxChnTime will
be set to default value.
