[PATCH] dinput: Increase device buffer size to 1024.

[Rémi Bernon]

The buffer size was previously limited to 20 in:

  8d052561724f9c8d9e7770964bfaebdd01e98e60

Testing shows that it is somewhere around 1024 on Windows, and using a
smaller buffer causes some input data to be lost with high polling rate
mouses. It can be spotted in Wolfenstein II: New Colossus menus.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
