[dpdk-dev] lib/librte_mbuf: remove void * pointer cast

  It is unnecessary to cast from void * to struct rte_mbuf *,
the change can make code more simple.

Hi Zhiyong,

3 comments about patch formatting:

1/ the title must follow the convention seen in the git history.
If you use git log --oneline lib/librte_mbuf
you will see that it must start with "mbuf:"

2/ The * character does not play well when patch saved in a file,
and it is useless: "void pointer" is correct for understanding.

3/ You must Cc the maintainer as described in MAINTAINERS.
You can use devtools/get-maintainer.sh.
Here, I Cc Olivier.

Thanks

Drop this one since the patch doesn't follow the convention. I will resend another new one.

Thanks
