[Impact]
Some Asus laptops report "discharging" when the battery is full and AC
is plugged

[Test]
Charge battery to full, the issue appears.
Users report with the patch the behaviour is correct.

[Fix]
The discharge rate is 0 on those machines. Use that to detect the wrong
status report.

[Regression Potential]
Low. The quirk uses strict DMI to match affected systems.
