[PATCH 0/1] MR1841: hidclass.sys: Make sure a desktop is created for the driver process.

[Rémi Bernon]

This was previously automatically done when user32 was loaded, but since
the move of __wine_send_input to win32u, we do not need to load it any
more. Somehow it is still loaded when prefix is initialized or updated,
and the dinput tests work in some cases, but not in some other.

This makes sure we have a desktop or WM_INPUT messages won't be sent by
wineserver.
