spapr: don't migrate "spapr_option_vector_ov5_cas" to pre 2.8 machines
a324d6f16697 "spapr: Support ibm,dynamic-memory-v2 property" added a new feature in the set of CAS-negotiatable options. This causes the CAS-negotiated options subsection to be migrated, even for old machine types that don't know about it, and breaks backward migration to QEMU 2.7 and older versions: qemu-system-ppc64: error while loading state for instance 0x0 of device 'spapr' qemu-system-ppc64: load of migration failed: No such file or directory Since this feature only affects boot time behaviour, it should be filtered out when we decide to migrate CAS-negotiated options, like we already do with OV5_FORM1_AFFINITY and OV5_DRCONF_MEMORY.
