rtnetlink: fix error return code in rtnl_link_fill()
Fix to return a negative error code from the error handling case instead of 0(possible overwrite to 0 by ops->fill_xstats call), as returned elsewhere in this function. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: David S. Miller <davem@davemloft.net>
