net: hsr: reject unresolved interlink ifindex
In hsr_newlink(), a provided but invalid IFLA_HSR_INTERLINK attribute
was silently ignored if __dev_get_by_index() returned NULL. This leads
to incorrect RedBox topology creation without notifying the user.
Fix this by returning -EINVAL and an extack message when the
interlink attribute is present but cannot be resolved.
