qcacld-3.0: Fix treating channel id as frequency issue for SAP

There are CSA IE/beacon template cmd with duplicate IE COUNT: 10.
And interval of 2nd IE COUNT: 10 and IE COUNT: 9 is much less than
100 ms.
Radar is triggered,  tried to switch to channel 11, but set
target chan id 11 as frequency 11 wrongly,   frequency 11 is illegal
and disabled, then switch to new freq: 2412 again.
