[Python] Avoid InvalidStateError on cancel (#35380)
When the co-routine GetConnectedDevice() gets cancelled, the wait_for
call will cancel the future we are waiting for. However, the SDK still
calls the _DeviceAvailableCallback with an error (CHIP Error 0x00000074:
The operation has been cancelled). However, we can't set the future
result at this point as the co-routine is already cancelled.
Simply check the future state before setting the result.
