drm/i915: Reorder drm_vblank_put() vs. need_vlv_dsi_wa
Drop the vblank reference only after we've done the hideous
need_vlv_dsi_wa stuff. This will make it easier to reuse the
the vblank evasion machinery elsewhere.
Keeping the vblank reference for a bit longer is not a
problem. In fact we might want to not drop it at all until
intel_pipe_update_end(), but we'll leave that idea for later.
