rtlwifi: btcoexist: Fix breakage of ant_sel for rtl8723be
In commitbcd37f4a08
("rtlwifi: btcoex: 23b 2ant: let bt transmit when hw initialisation done"), there is an additional error when the module parameter ant_sel is used to select the auxilary antenna. The error is that the antenna selection is not checked when writing the antenna selection register. Fixes:bcd37f4a08
