When commit bd2270608fa0 ("migration/ram.c: add a notifier chain for precopy") added PRECOPY_NOTIFY_SETUP notifiers at the end of qemu_savevm_state_setup(), it didn't take into account a possible error in the loop calling vmstate_save() or .save_setup() handlers.
Check ret value before calling the notifiers.
