Jesse Barnes 83f7fd055e drm/i915: don't queue flips during a flip pending event 
Hardware will set the flip pending ISR bit as soon as it receives the
flip instruction, and (supposedly) clear it once the flip completes
(e.g. at the next vblank).  If we try to send down a flip instruction
while the ISR bit is set, the hardware can become very confused, and we
may never receive the corresponding flip pending interrupt, effectively
hanging the chip.
