vfio: Avoid error_propagate() after migrate_add_blocker()
When migrate_add_blocker(blocker, &err) is followed by error_propagate(errp, err), we can often just as well do migrate_add_blocker(..., errp). This is the case in vfio_migration_probe(). Prior art: commit 386f6c07d2 "error: Avoid error_propagate() after migrate_add_blocker()".
