The rte_pktmbuf_dump should display offset, refcount, and vlan
info since these are often useful during debugging.

v3 - only display vlan tci if offload flags say it is there
     display packet type
v2 - remove casts, change in_port to port
     the refcount and offset are property of per-segment
