[ofa-general] ibv_post_send fails when using malloc in a special way

I'm not sure how madvise() would have any relevance to your problem,
since as far as I can see you are not using fork().  In any case,
libibverbs will only call madvise() if you call ibv_fork_init() or set
the IBV_FORK_SAFE environment variable.
