Steve Sistare 094a3dbc55 migration: ram block cpr blockers 
Unlike cpr-reboot mode, cpr-transfer mode cannot save volatile ram blocks
in the migration stream file and recreate them later, because the physical
memory for the blocks is pinned and registered for vfio.  Add a blocker
for volatile ram blocks.

Also add a blocker for RAM_GUEST_MEMFD.  Preserving guest_memfd may be
sufficient for CPR, but it has not been tested yet.
