[PATCH v3 19/27] net/iavf: avoid rte malloc in RSS configuration

[Anatoly Burakov]

Currently, when configuring RSS (redirection table, lookup table, and
hash key), we are using rte_zmalloc followed by an immediate rte_free.
This is not needed as this memory is not being stored anywhere, so
replace it with regular malloc/free.
