[Qemu-devel] [PATCH RFC v7 7/9] migration: remove unused &local_err parameter in migrate_set_error

[Fei Li]

Always call migrate_set_error() to set the error state without relying
on whether multifd_save_cleanup() succeeds. As the passed &local_err
is never used in multifd_save_cleanup(), remove it.
