In order to keep the assert_bind_count() valid, we need to hold the vma page reference until after we drop the bind count. However, we must also keep the drm_mm_remove_node() as the last action of i915_vma_unbind() so that it serialises with the unlocked check inside i915_vma_destroy(). So we need to split up i915_vma_remove() so that we order the detach, drop pages and remove as required during unbind.
