Zero out Cumulus related virtual address attribute during MPIPL

During MPIPL we want to zero out virtual address attributes because
we want to insure they get recomputed on the MPIPL pass through
the isteps. These values can change between boots so its important
to recompute them on the MPIPL pass.
