[Intel-gfx] [PATCH] drm/i915: Remove src adjustment in intel_check_sprite_plane.

[Maarten Lankhorst]

The rounding can cause a perfectly normal 16x16 src to full-screen
dst to be rounded down, even without clipping involved. Because of
this we should just remove the adjustment, as no other driver or plane
does it.
