From: David Ahern <dsah...@gmail.com>
'ip ru flush' currently removes all rules with priority > 0 regardless
of any other command line arguments passed in. Update flush_rule to
call filter_nlmsg to determine if the rule should be flushed or not.
This enables rule flushing such as 'ip ru flush table 1001' and
'ip ru flush pref 99'.
