fix uninitialized property

When the robot is idle, parked at the base, and I call
`kh.get_device_properties(dev)`, I get back the following backtrace
(after removing some asyncio layers due to awaits):

   File "/nix/store/asiphbpiy2gmidfm3xbwcikayhs66289-python3-3.11.7/lib/python3.11/dataclasses.py", line 240, in wrapper
     result = user_function(self)
              ^^^^^^^^^^^^^^^^^^^
   File "<string>", line 3, in __repr__
 AttributeError: 'DeviceProperties' object has no attribute 'net_status'. Did you mean: 'net_stauts'?

What's particularly funny is that when run as `python -m asyncio`, to
get the `await` working in the REPL, the exception does not contain that
useful hint, and it looks like the following instead:

 >>> kh.get_device_properties(d[0])
 Traceback (most recent call last):

              ^^^^^^^^^^^^^^^^^^^

Anyway, the root cause was just a typo in DeviceProperties.__init__.
