net: hsr: allow PRP RedBox (interlink) creation

Browse Source 
With the PRP interlink datapath, duplicate discard and supervision support
in place, a PRP device can act as a RedBox. Remove the rtnetlink rejection
of "type hsr ... interlink <dev> proto 1"; the feature is implemented
unconditionally by the preceding patches.
