wifi: rtw89: coex: Parsing Wi-Fi firmware error message from reports 



Parsing firmware error message from original version and v1 reports to
show up exception counter of commands from firmware in debug message.
Then, we can make sure exchange commands are correct totally.

In the later version Wi-Fi firmware(v1), the report format was changed.
With this update, we can yield correct report from proper struct.
