svn commit: r323786 - head/sys/net

New Revision: 323786
URL: https://svnweb.freebsd.org/changeset/base/323786

Log:
  In r288122, we changed vm_page_unwire() so that it returns a Boolean
  indicating whether the page's wire count transitioned to zero.  Use that
  return value in zbuf_page_free() rather than checking the wire count.
