qcacmn: Use min rest time same as max rest time in SAP+STA case

In SAP+STA case the min rest time is 50 and thus during scan
possibility increases that the device is not present in base channel
during the time of beacon transmission and thus beacons are not
transmitted.

Thus if SAP is present the min rest time should be 100ms
max rest time), so that during scan device can come to base channel
and transmit beacons.
