wifi: rtw89: coex: add debug message of link counts on 2/5GHz bands for wl_info v7

The counts will be used by MLO, and it is ongoing to add the code, so add
debug message in todo part to avoid warnings reported by clang:

coex.c:6323:23: warning:
	 variable 'cnt_2g' set but not used [-Wunused-but-set-variable]
 6323 |         u8 i, mode, cnt = 0, cnt_2g = 0, cnt_5g = 0, ...
      |                              ^
coex.c:6323:35: warning:

      |                                          ^
