Subject: rtlwifi: rtl8821ae: Fix an expression that is always false

From: Larry Finger <[email protected]>

commit 251086f588720277a6f5782020a648ce32c4e00b upstream.

In routine _rtl8821ae_set_media_status(), an incorrect mask results in a test for AP status to always be false. Similar bugs were fixed in rtl8192cu and rtl8192de, but this instance was missed at that time.
