mempool: remove physical address aliases

Remove the deprecated unioned fields physaddr and phys_addr
from the structures rte_mempool_objhdr and rte_mempool_memhdr.
They are replaced with the fields iova which are at the same offsets.

Remove the deprecated macro MEMPOOL_F_NO_PHYS_CONTIG
which is an alias of the more recent MEMPOOL_F_NO_IOVA_CONTIG.
