enable per cpu caches on the mbuf pools.
this didnt make sense previously since the mbuf pools had item
limits that meant the cpus had to coordinate via a single counter
to make sure the limit wasnt exceeded.
mbufs are now limited by how much memory can be allocated for pages
from the system. individual pool items are no longer counted and
therefore do not have to be coordinated.
ok bluhm@ as part of a larger diff.
