72514b5d55 ethdev: fix check of threshold for Tx freeing
The parameter tx_free_thresh is not consistent between the drivers:
some use it as rte_eth_tx_burst() requires, some release buffers when
the number of free descriptors drop below this value.
Let's use it as most fast-path code does, which is the latter, and update
comments throughout the code to reflect that.

b35d0d80f0 ixgbe: check mbuf refcnt when clearing a ring
The function to clear the TX ring when a port was being closed, e.g. on
exit in testpmd, was not checking the mbuf refcnt before freeing it.
Since the function in the vector driver to clear the ring after TX does
not set the pointer to NULL post-free, this caused crashes if mbuf
debugging was turned on.

To reproduce the issue, ensure the follow config variables are set:
RTE_IXGBE_INC_VECTOR
RTE_LIBRTE_MBUF_DEBUG
Then compile up and run testpmd using 10G ports with the vector driver.
Start traffic and let some flow through, then type "stop" and "quit" at
the testpmd prompt, and crash will occur. Output below:

	testpmd> quit
	Stopping port 0...done
	Stopping port 1...PANIC in rte_mbuf_sanity_check():
	bad ref cnt

4ca29c87ed ixgbe: use cold attribute
As well as the fast-path functions in the rxtx code, there are also
functions which set up and tear down the descriptor rings. Since these
are not performance critical functions, there is no need to have them
extensively optimized, so we add __attribute__((cold)) to their
definitions. This has the side-effect of making debugging them easier as
the compiler does not optimize them as heavily, so more variables are
accessible by default in gdb.

b8bc1241d1 mlx4: shrink Tx queue elements for better performance
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().
