util: vfio-helpers: Factor out and fix processing of existing ram blocks
Factor it out into common code when a new notifier is registered, just
as done with the memory region notifier. This keeps logic about how to
process existing ram blocks at a central place.
Just like when adding a new ram block, we have to register the max_length.
Ram blocks are only "fake resized". All memory (max_length) is mapped.
Print the warning from inside qemu_vfio_ram_block_added().
