dinput: Increase device buffer size to 1024.

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.
