fix(greylag): disable USB autosuspend

Sometimes TLP has an issue where it incorrectly disables my USB devices
while I am still using them. This is a pain, as it means that I can no
longer use my computer without un-suspending them.

Let's disable the buggy feature so this is no longer a problem, the power
tradeoff is likely negligible in comparison to the convenience I will
gain
