wifi: rtw89: avoid stringop-overflow warning
After -Wstringop-overflow got enabled, the rtw89 driver produced
two odd warnings with gcc-13:
drivers/net/wireless/realtek/rtw89/coex.c: In function 'rtw89_btc_ntfy_scan_start':
drivers/net/wireless/realtek/rtw89/coex.c:5362:50: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
5362 | wl->dbcc_info.scan_band[phy_idx] = band;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~

I don't know what happened here, but adding an explicit range check
shuts up the output.
