dbuf_evict_notify() does not need dbuf_evict_lock
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.
