Bluez lowenergy peripheral incomplete initialization

The Bluez lowenergy peripheral (aka "server") has an unintended early return in one of its initializing functions, which left the initialization partially incomplete.

This doesn't prevent the most typical operation against the server, but impacts degenerately following areas:

• Connection update requests won't work
• Signing data handling
• Gatt timeout setting (BLUETOOTH_GATT_TIMEOUT env variable)
