drm/vmwgfx: Fix error handling in get_node
ttm_mem_type_manager_func.get_node was changed to return -ENOSPC instead of setting the node pointer to NULL. Unfortunately vmwgfx still had two places where it was explicitly converting -ENOSPC to 0 causing regressions. This fixes those spots by allowing -ENOSPC to be returned. That seems to fix recent regressions with vmwgfx.
