Input: xpad - fix support for some third-party controllers

Some third-party controllers, such as the HORPIAD FPS for Nintendo Switch and
Gamesir-G3w, require a specific packet that the first-party XInput driver sends
before it will start sending reports. It's not currently known what this packet
does, but since the first-party driver always sends it's unlikely that this
could cause issues with existing controllers.
