[Intel-gfx] [PATCH] drm/i915: Call i915_gem_suspend() only after display is turned off

[José Roberto de Souza]

Gem buffers could still be in use by display after i915_gem_suspend()
is executed so there is chances that i915_gem_flush_free_objects()
will be being executed at the same time that
intel_runtime_pm_driver_release() is executed printing warnings about
wakerefs will being held.

So here only calling i915_gem_suspend() and by consequence
i915_gem_drain_freed_objects() only after display is down making
sure all buffers are freed.
