[dpdk-dev] net/i40e: fix hash input set issue on X722

Since there are some new pctypes on X722, but recently they have
not been announced on the RTE lib, so if it can not correspondently
set hash input set for these packet type, the hash function won’t
work. So we need to handle them base on the translation of the new
PCTYPE and the original PCTYPE.

Fixes: b6a0ec418274 ("i40e: use AQ for Rx control register read/write")
