[dpdk-dev] [DPDK] net/i40e: fix RSS hash update problem for X722 VF

[penghuan]

This patch fixes X722 VF problem when received packet don't have
HASH value.
1) Packet classifier types update should support X722 VF, not only
 for X722 PF;
2) MAC type is invalid for X722 VF when set packet classifier type,
so move it after MAC type is set correctly;
