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().
