History
mav 7ddbc411f2 Do not ignore arc_adjust() return value. 
This covers scenario when ARC may not shrink as fast as it could:
1. arc_size < arc_c and arc_adjust() does not evict anything, returning
   zero to arc_reclaim_thread();
2. arc_available_memory() reports memory pressure, which can not be
   satisfied by arc_kmem_reap_now();
3. arc_shrink() reduces arc_c and calls arc_adjust(), return of which is
   ignored;
4. even if the last arc_adjust() could not satisfy arc_size < arc_c,
   arc_reclaim_thread() will still go to sleep, since the first one
   returned zero.
