The supervision address is read-only. It is constructed by kernel and
only the last byte can be modified by setting the multicast-spec as
documented indeed.
As 1.46 was not released yet, we still can drop the whole API for this
setting property. We are keeping the NMDeviceHsr property as it is a
nice to have for reading it.
