Thomas Chou ee02a4ef40 ethoc: fix null dereference in ethoc_probe
Dan reported the patch 0baa080c75c: "ethoc: use system memory
as buffer" introduced a potential null dereference.

  1060  free:
  1061          if (priv->dma_alloc)
                    ^^^^^^^^^^^^^^^
	priv can be null here.

He also suggested that the error handling is not complete.

This patch fixes the null priv issue and improves resources
releasing in ethoc_probe() and ethoc_remove().
