Subject: [PATCH ethtool v2 05/13] ethtool: fix extra warnings

'$ scan-build make' reports

netlink/permaddr.c:44:2: warning: Value stored to 'ifinfo' is never read [deadcode.DeadStores]
        ifinfo = mnl_nlmsg_put_extra_header(nlhdr, sizeof(*ifinfo));
        ^        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So just remove the extra assignment which is never used.
