TAILQ_ENTRY next is not needed in struct mbuf_dynfield_elt and
mbuf_dynflag_elt, since they are actually chained by rte_tailq_entry's
next field when calling TAILQ_INSERT_TAIL(mbuf_dynfield/dynflag_list, te,
next).

I found this issue when reading the mbuf dynfiled/dynflag feature code,
mbuf_autotest is passed with this change, though I may miss something or
this filed has some special design purpose, please correct me if I am
wrong.
