TX queue elements (struct txq_elt) contain WR and SGE structures required by
ibv_post_send(). This commit replaces them with a single pointer to the
related TX mbuf considering that:
- There is no need to keep these structures around forever since the
hardware doesn't access them after ibv_post_send() and send_pending*()
have returned.
- The TX queue index stored in the WR ID field is not used for completions
anymore since they use a separate counter (elts_comp_cd).
- The WR structure itself was only useful for ibv_post_send(), it is
currently only used to store the mbuf data address and an offset to the
mbuf structure in the WR ID field. send_pending*() callbacks only require
SGEs or buffer pointers.
Therefore for single segment mbufs, send_pending() or send_pending_inline()
can be used directly without involving SGEs. For scattered mbufs, SGEs are
allocated on the stack and passed to send_pending_sg_list().
