Avihai Horon 08fc4cb517 migration: Add .save_prepare() handler to struct SaveVMHandlers ...

Add a new .save_prepare() handler to struct SaveVMHandlers. This handler
is called early, even before migration starts, and can be used by
devices to perform early checks.

Refactor migrate_init() to be able to return errors and call
.save_prepare() from there.
