    sna: Fix direction flags for memmove

    Under a compositor, the current deltas may invert the sense of the copy
    direction, causing scrolling corruption. Simplify handling those flags
    by making them invariant for the function.

That should fix the scrolling. The jury is still out as for the cause of the
other type of corruption.
