Add a new zone flag UMA_ZONE_MTXCLASS. This puts the zone in it's own
mutex class. Currently this is only used for kmapentzone because kmapents
are are potentially allocated when freeing memory. This is not dangerous
though because no other allocations will be done while holding the
kmapentzone lock.
