[PATCH] hidclass.sys: Overwrite queued reports as FIFO instead of LIFO.

[Rémi Bernon]

Based on a patch from Ivo Ivanov <logos128 at gmail.com>.

The issue causes severe skipping and non smooth movement tracking in
apps/games, when the HidP/HidD APIs are used to control the device
(joysticks, controllers, steering wheels, etc.).

Usually such devices use constant stream of INPUT reports to report
their coords, so any report skipping or change of the sequence,
when the interested apps are reading, would lead to such issues.
