mlx4_core: Fix possible bad free in mlx4_buf_free() When mlx4_buf_free() is called from the error path of mlx4_buf_alloc(), it may be passed a buffer structure that does not have all pages filled in. Add a check for NULL to mlx4_buf_free() so we avoid passing NULL to dma_free_coherent() (which will crash).
