analyze-migration.py: Remove trick on parsing ramblocks
RAM_SAVE_FLAG_MEM_SIZE contains the total length of ramblock idstr to know whether scanning of ramblocks is complete. Drop the trick. Reviewed-by: Fabiano Rosas <farosas@suse.de> Link: https://lore.kernel.org/r/20240117075848.139045-4-peterx@redhat.com Signed-off-by: Peter Xu <peterx@redhat.com>
