rtlwifi: btcoexist: Fix antenna selection code

In commit 87d8a9f35202 ("rtlwifi: btcoex: call bind to setup btcoex"),
the code turns on a call to exhalbtc_bind_bt_coex_withadapter(). This
routine contains a bug that causes incorrect antenna selection for those
HP laptops with only one antenna and an incorrectly programmed EFUSE.
These boxes are the ones that need the ant_sel module parameter.
