drm/vmwgfx: Return 0 when gmrid::get_node runs out of ID's



commit 4b9ce3a651a37c60527101db4451a315a8b9588f upstream.

If it's not a system error and get_node implementation accommodate the
buffer object then it should return 0 with memm::mm_node set to NULL.

v2: Test for id != -ENOMEM instead of id == -ENOSPC.
