[Mesa-dev] [PATCH v2 3/6] i965/blit: Remove a bogus assertion

[Jason Ekstrand]

This assertion, while valid for linear buffers, doesn't work properly for
tiled memory.  It used to work most of the time because the offset provided
was always to the left-hand edge of the image.  However, if you use a byte
offset to get to the inside of the image, the height * stride calculation
may actually end up being too large.
