[PATCH v2 15/26] net/i40e: avoid rte malloc in DDP ptype handling

[Anatoly Burakov]

Currently, when updating customized protocol and packet type information
via DDP packages, we are using rte_zmalloc followed by immediate rte_free.
This is not needed as these buffers are only used temporarily within
the function scope, so replace it with regular malloc/free.
