Mark Johnston 06d8bdcbf7 uma: Use the bucket cache for cross-domain allocations 
uma_zalloc_domain() allocates from the requested domain instead of
following a first-touch policy (the default for most zones).  Currently
it is only used by malloc_domainset(), and consumers free returned items
with free(9) since r363834.

Previously uma_zalloc_domain() worked by always going to the keg for an
item.  As a result, the use of UMA zone caches was unbalanced: we free
items to the caches, but always allocate from the keg, skipping the
caches.

Make some effort to allocate from the UMA caches when performing a
cross-domain allocation.  This avoids blowing up the caches when
something is performing many transient allocations with
malloc_domainset().
