Bluetooth: hci_event: Disconnect device when BIG sync is lost
When a BIG sync is lost, the device should be set to "disconnected". This ensures symmetry with the ISO path setup, where the device is marked as "connected" once the path is established. Without this change, the device state remains inconsistent and may lead to a memory leak.
