Handle inter-node HRMOR correctly on 3/4 nodes
Recent changes to direclty use HRMOR for calculating
addresses broke 3 and 4 node configs. This commit
removes the multiplication of _nodal_ HRMOR * group id
(since the _nodal_ HRMOR mechanism now factors that in).
It also uses the IPC addresses to handle start payload,
so math/constants are not used to find master node.
