[PATCH v2 05/20] mbuf: remove PKT_TX_UDP_TUNNEL_PKT flag

[Olivier Matz <olivier.matz-pdR9zngts4EAvxtiuMwx3w@public.gmane.org>]

Since previous commit, this flag is not used by any PMD, remove it from
mbuf API and from csumonly (testpmd). In csumonly, the
PKT_TX_OUTER_IP_CKSUM flag is already set for vxlan checksum, providing
enough information to the underlying driver.
