    sna: Fix the relocation dword for stippled_1_blt

    We were telling the kernel the correct location for it to fill the
    64b relocation, but we were writing the presumed offset into the wrong
    pair of dwords in the batch ourselves. For the frequent case where we
    used a new upload buffer, the kernel would perform the fixup and correct
    our mistake, but if we happened to reuse a buffer then we told the gpu
    to source the stipple from the wrong address.

fixed the issue that occurred for me with openjdk-8 and disabling RENDER.
Hopefully this is the one you hit as well!
