[PATCH v5 24/27] net/ice: avoid rte malloc in RSS RETA operations

[Anatoly Burakov]

Currently, when updating or querying RSS redirection table (RETA), 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.
