mlx4: fix 32-bit build
Fix warning messages "cast to pointer from integer of different size" when
compiling DPDK in 32 bit with Mellanox PMD.
SGE addresses are 64 bit integers, converting them to pointers must be done
through uintptr_t to avoid compilation warnings when those have a different
size.

mbuf: optimize refcnt update
In __rte_pktmbuf_prefree_seg(), there was an optimization to avoid using
a costly atomic operation when updating the mbuf reference counter if
its value is 1. Indeed, it means that we are the only owner of the mbuf,
and therefore nobody can change it at the same time.
We can generalize this optimization directly in rte_mbuf_refcnt_update()
so the other callers of this function, like rte_pktmbuf_attach(), can
also take advantage of this optimization.

Indeed there is problem at ACL build stage.
Sometimes acl_merge_trie() is too aggressive in trying to conserve
space at build time.
So it takes a wrong assumptions and didn't duplicate a node,
even when it should.
