sna: Do not force ping-pong migration for TearFree + NoAccel

If acceleration is disabled, but we are using TearFree, then ideally we
want to flip the shadow buffer onto the scanout. If the shadow buffer is
already on the GPU, e.g. having been swapped in by a compositor, then we
do not want to move it to the CPU domain only to copy it back to a new
buffer and then flipped for a TearFree update.
