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

RH-Commit: [29/50] fcaeb0e07cf828f3cd0d115515b30d913525a0a2 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_block()
to be consistent with all other capabilities.
