Subject: rtlwifi: btcoexist: Fix breakage of ant_sel for rtl8723be

From: Larry Finger <[email protected]>

commit a33fcba6ec01efcca33b1afad91057020f247f15 upstream.

In commit bcd37f4a0831 ("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.
