I think you need to independently check the return value from
rte_dma_get_dev_id, rather than assuming when it returns an error value the
resultant index location will hold a null pointer.

The rte_dma_pmd_allocate function reserves memory for the private data, so
the release function should free that memory too. However, you have
assigned private_data to NULL just above, so that probably won't work.
