rtlwifi: btcoexist: Fix breakage of ant_sel for rtl8723be

commit a33fcba6 upstream.

In commit bcd37f4a ("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: bcd37f4a ("rtlwifi: btcoex: 23b 2ant: let bt transmit when hw initialisation done")
