spapr/drc: don't migrate DRC of cold-plugged CPUs and LMBs 

As explained in commit 5c0139a8c2 ("spapr: fix default DRC state for
coldplugged LMBs"), guests expect cold-plugged LMBs to be pre-allocated
and unisolated. The same goes for cold-plugged CPUs.

While here, let's convert g_assert(false) to the better self documenting
g_assert_not_reached().
