net/iavf: fix gtpu extension flow error
Checks
Commit Message
From: Wenxuan Wu <wenxuanx.wu@intel.com>
Due to the change of struct rte_gtp_psc_generic_hdr, firmware can
not handle gtp_psc properly, we induce a new structure to fix this
gap between firmware and struct rte_gtp_psc_generic_hdr.

Why this is related firmware? iavf rte_flow is not related with firmware, it is about virtchnl between VF and PF
