IB/mlx4: Lock SQ lock in mlx4_ib_post_send()
Because of a typo, mlx4_ib_post_send() takes the same lock rq.lock as mlx4_ib_post_recv(). Correct the code so the intended sq.lock is taken when posting a send. Noticed by Yossi Leybovitch and pointed out by Jack Morgenstein from Mellanox. Signed-off-by: Roland Dreier <rolandd@cisco.com>
