workqueue: Fold rebind_worker() within rebind_workers() 

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2182337

    workqueue: Fold rebind_worker() within rebind_workers()

    !CONFIG_SMP builds complain about rebind_worker() being unused. Its only
    user, rebind_workers() is indeed only defined for CONFIG_SMP, so just fold
    the two lines back up there.
