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().
