fix: prevent disconnecting same audio device during connection

Fix a bug where connecting a Bluetooth audio device could cause it to be
disconnected immediately due to incorrect conflict detection. The code
was comparing devices without checking if they were the same device,
leading to self-disconnection.

Added address comparison in both connectProperties() and doConnect()
methods to ensure that when checking for conflicting connected audio
devices, the system doesn't mistakenly identify the current device as a
conflict and disconnect it. This prevents the undesirable behavior where
users see a disconnect notification followed by a connect notification
when first pairing audio devices.

Influence:
1. Test connecting Bluetooth audio devices for the first time
2. Verify no disconnection notifications appear during initial
connection
3. Test multiple audio device connections and switching between them
4. Check that legitimate conflicts (different devices) still trigger
proper disconnection
5. Verify connection stability with various Bluetooth audio profiles

fix: 修复连接过程中误断开同一音频设备的问题

修复了连接蓝牙音频设备时可能因冲突检测错误导致立即断开的问题。原代码在比
较设备时未检查是否为同一设备，导致设备自断开。

在 connectProperties() 和 doConnect() 方法中都添加了地址比较，确保在检查
冲突的已连接音频设备时，系统不会错误地将当前设备识别为冲突并断开连接。这
解决了用户首次配对音频设备时看到先断开后连接通知的不良体验。

Influence:
1. 测试首次连接蓝牙音频设备
2. 验证初始连接过程中不会出现断开通知
3. 测试多个音频设备连接及切换
4. 检查合法的设备冲突（不同设备）仍能正确触发断开
5. 验证各种蓝牙音频配置文件的连接稳定性
