net/hns3: fix some packet types

Browse Source 
Currently, the packet type calculated by
vlan/ovlan/l3id/l4id/ol3id/ol4id fields have the following problems:
1) Identify error when exist VLAN strip which will lead to the data
   buffer has non VLAN header but mbuf's ptype have L2_ETHER_VLAN flag.
2) Some packet identifies error, eg: hardware report it's RARP or
   unknown packet, but ptype will marked with L2_ETHER .

So driver will calculate packet type only by l3id/l4id/ol3id/ol4id
fields.

Fixes: 0e98d5e6d9 ("net/hns3: fix packet type report in Rx")
Fixes: bba6366983 ("net/hns3: support Rx/Tx and related operations")
