runqemu-ifdown: ensure to clean up TAP
In runqemu-ifup, ip command is used to add TAP; in runqemu-ifdown, we should do the reversed logic, using ip command to delete TAP, to make sure TAP is cleaned up by ourselves. I can see that in runqemu-ifdown script, 'tunctl -d' and 'iptables' commands are used to deal with TAP, but these two commands cannot make sure that the TAP is cleaned up. runqemu-ifup uses 'ip' to set up TAP, we really need to do the opposite in runqemu-ifdown.
