wifi: rtw89: correct 5 MHz mask setting
[ Upstream commit d33fc8d0368c180fe2338bfae4f5367a66a719f4 ]
Use primary channel index to determine which 5 MHz mask should be enable.
This mask is used to prevent noise from channel edge to effect CCA
threshold in wide bandwidth (>= 40 MHZ).
Fixes: 1b00e9236a71 ("rtw89: 8852c: add set channel of BB part")
Fixes: 6b0698984eb0 ("wifi: rtw89: 8852b: add chip_ops::set_channel")
