WiFi 2x2 + BT combo cards can be two or three physical antenna. For two
antenna case, one antenna is shared by WiFi and BT, and different
configuration should be applied. Fix the typo.
This problem was found by Coccicheck, and actually that is a typo instead:

BTW for Closes and Link tags it's better to use a direct lore link with
Message-Id:
Closes: https://lore.kernel.org/linux-wireless/[email protected]/
The benefits are:
* as the Message-Id is in the link, the mail can be found even if
lore.kernel.org would go away
* it's shorter
* regzbot uses the Message-Id to close the issues
In lore you can get the URL from "permalink" link. I changed the link
during commit, so no need to resend.
