Although the physical address won't be correct in memory segment,
this allows at least to retrieve the physical address using
rte_mem_virt2phy(). Indeed, if the page is not locked, the page
may not be present in physical memory.
With next commit, it allows a mempool to have properly filled physical
addresses when using --no-huge option.
