drm/qxl: fix cursor position with non-zero hotspot

Browse source

commit d59a1f71ff upstream.

The SPICE protocol considers the position of a cursor to be the location
of its active pixel on the display, so the cursor is drawn with its
top-left corner at "(x - hot_spot_x, y - hot_spot_y)" but the DRM cursor
position gives the location where the top-left corner should be drawn,
with the hotspot being a hint for drivers that need it.

This fixes the location of the window resize cursors when using Fluxbox
with the QXL DRM driver and both the QXL and modesetting X drivers.
