[PATCH v6 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 memory does not need to be stored in hugepage memory, and in context
of IAVF we do not define how big these structures can be, so replace the
allocations with regular malloc/free.
