Andriy Gapon 667002fa27 MFV r319741: 8156 dbuf_evict_notify() does not need dbuf_evict_lock
illumos/illumos-gate@dbfd9f9300
dbfd9f9300

https://www.illumos.org/issues/8156
  dbuf_evict_notify() holds the dbuf_evict_lock while checking if it should do
  the eviction itself (because the evict thread is not able to keep up).
  This can result in massive lock contention.
  It isn't necessary to hold the lock, because if we make the wrong choice
  occasionally, nothing bad will happen.
