I was influenced by a warning saying "rte_mempool_get_page_size is
flagged as experimental but is not listed in version map", but actually
it should not be flagged as experimental. I'll remove both.

My friend also suggested me to add it in a private header, which is a
good idea, but I think it should be in another patch because there are
already several functions in this case.
