Since AVL already has embedded element counter, use dn_dbufs_count only for dbufs not counted there (bonus buffers) and just add them. This removes two atomics per dbuf life cycle. According to profiler it reduces time spent by dbuf_destroy() inside bottlenecked dbuf_evict_thread() from 13.36% to 9.20% of the core.
