fix half of the controls not working on steam deck

[Dark3clipse]

In this PR I reverted to the old way of swapping old_state and _input variables. For some reason the "new" way makes half the SD controls non-functional.

I kept the gyro groll inversion. I tested it with yuzu and Kirby and the forgotten land in the minigame and the gyro seems correct.

The only difficulty I still had was that for some reason with my SD the yaw updates with a rather large lag of ~2 seconds. I don't know if this is related to my hardware or whether more people have this problem.

I'll get the change merged later. Not sure why the Yaw would lag behind the Roll or Pitch. I think I have mainly tested it with the DS4 and I did not experience a problem like that with CemuHook (using PadTest app in Wine). I can only assume it is something specific to the steamdeck module.

Edit: Remembered later that I have tested CemuHook with the Steam Controller in the past

So much for getting this merged quickly. I am spread too thin online and AFK. Thank you for fixing Steam Deck mapping.
