    [i915] Prevent recursive batchbuffer flushing.
    
    Workaround for recursive batchbuffer flushing: If the window is
    moved, we can get into a case where we try to flush during a
    flush.  What happens is that when we try to grab the lock for
    the first flush, we detect that the window moved which then
    causes another flush (from the intel_draw_buffer() call in
    intelUpdatePageFlipping()).  To work around this we reset the
    batchbuffer tail pointer before trying to get the lock.  This
    prevent the nested buffer flush, but a better fix would be to
    avoid that in the first place.
