We are fixing it host side, I still think we need hack the guest until it knows
the host has the workaround,

Daniel Vetter suggested we take a different path for atomic page flip, and
put back the copy mechanism until we can support atomic modesetting properly,
which might be simpler than reverting all the qxl atomic work.
