net/mlx: fix IPv4 and IPv6 packet type

Mellanox PMDs do not differentiate IP header with or without options, so
the advertised packet type for an IPv4 should not be RTE_PTYPE_L3_IPV4,
which explicitly means "does not contain any header option".

Change the driver to set
RTE_PTYPE(_INNER)_L3_IPV4_EXT_UNKNOWN or
RTE_PTYPE(_INNER)_L3_IPV6_EXT_UNKNOWN flags for all IPv4/IPv6 packets
received.

Fixes: 429df3803a16 ("mlx4: replace some offload flags with packet type")
Fixes: 67fa62bc672d ("mlx5: support checksum offload")
