tests/kms_flip: Make flip-vs-panning-vs-hang change DSPSURF
Make sure DSPSURF will change during the panning operation
in flip-vs-panning-vs-hang.
This will now test agains bugs between the kernel's mmio vs.
CS flip race handling and GPU resets. If the kernel is buggy
if will fail to notice that the panning operation changed the
base address before the GPU reset had a chance to deal with the
pending page flips, and so the flip would never complete due to
DSPSURFLIVE not matching the expected value.
