markj ff73b014ac Fix UMA's first-touch policy on systems with empty domains. 
Suppose a thread is running on a CPU in a NUMA domain with no physical
RAM.  When an item is freed to a first-touch zone, it ends up in the
cross-domain bucket.  When the bucket is full, it gets placed in another
domain's bucket queue.  However, when allocating an item, UMA will
always go to the keg upon a per-CPU cache miss because the empty
domain's bucket queue will always be empty.  This means that a non-empty
domain's bucket queues can grow very rapidly on such systems.  For
example, it can easily cause mbuf allocation failures when the zone
limit is reached.

Change cache_alloc() to follow a round-robin policy when running on an
empty domain.
