Fix flakiness when BluetoothDevice is not initialized

In some rare cases the BluetoothDevice is not initialized and we cannot
set the metadata:
12-08 19:52:32.647 31591 31690 E BluetoothDevice: Bluetooth is not
enabled. Cannot set metadata
It is ok to drop the checks in this situations since we rely entirely
on the set metadata

Test: adb shell device_config put media_audio android.media.audio.automatic_bt_device_type true
Test: atest AudioDeviceBrokerTest
Bug: 309477003
