... but the arcbuf_addref() function
served a second undocumented purpose of updating the ARC access
information when taking a hold on a dbuf. Without this logic
in place a cached dbuf would not migrate its associated
arcbuf_hdrt to the MFU list. This would negatively impact
the ARC hit rate, particularly on systems with a small ARC.
