Reorganize and fix monitor resume after migration
If migration failed in migrate_fd_put_buffer, the monitor may have been resumed not only in the error path of that function but also once again in migrate_fd_put_ready which is called unconditionally by migrate_fd_connect. Fix this by establishing a cleaner policy: the monitor shall be resumed when the migration file is closed, either via callback (migrate_fd_close) or in migrate_fd_cleanup if no file is open (i.e. no callback invoked).
