Add a check for device != null on commissioning.

[cecille]

Problem

Calling commission before establishing a pase session causes a seg fault

Change overview

• adds a null check to the device

Testing

Connect function on chip-device-ctrl still works, commission call no longer seg faults if you don't first establish a pase connection.
