Use the correct refresh function for device batteries which aren't of a
known type. This fixes battery information not getting updated on many
Logitech wireless devices.

Reproducer:
- Unplug Logitech receiver
- Replug Logitech receiver
- Press button on Logitech keyboard
- Move mouse/touchpad

The touchpad battery would be stuck in "unknown" and with a "type" of
battery. This commit forces the correct refresh function to be used, one
that reads the capacity_level on those devices, and will update the
overall battery level.
