RH-Author: Peter Xu <peterx@redhat.com>
RH-MergeRequest: 162: migration: Pretty failures for postcopy on unsupported memory types

RH-Commit: [23/50] 4809b1091edee38bd222af41b6313133705785c7 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_colo() to be
consistent with all other capabilities.
