Subject: [PATCH 3/5] bluez: add basic check for nil monitor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If PipeWire is built without Bluetooth support, then

`monitor = SpaDevice("api.bluez5.enum.dbus", monitor_props)`

will result in a nil monitor. This commit adds a basic sanity check
to avoid further using the nil variable.

Thanks-to: Pascal Flöschel (initial bug report)
