netdevsim: allow two netdevsim ports to be connected
Add two netdevsim bus attribute to sysfs:
/sys/bus/netdevsim/link_device
/sys/bus/netdevsim/unlink_device
Writing "A M B N" to link_device will link netdevsim M in netnsid A with
netdevsim N in netnsid B.
Writing "A M" to unlink_device will unlink netdevsim M in netnsid A from
its peer, if any.
rtnl_lock is taken to ensure nothing changes during the linking.
