8   Remove a node from the offset manager. If the node wasn't added before, this
9   does nothing. After this call returns, the offset and size will be 0 until a
10   new offset is allocated via <code class="function">drm_vma_offset_add</code> again. Helper functions like
11   <code class="function">drm_vma_node_start</code> and <code class="function">drm_vma_node_offset_addr</code> will return 0 if no
12   offset is allocated.
