i915: Enable IMR passthrough of vblank events before enabling it in pipestat. Otherwise, if we lost the race, the pipestat bit would be set without being reflected in IIR, and we would never clear the pipestat bit so the pipe event would never be generated again, and all vblank waits would time out.
