    Don's try to restart dracut-initqueue if it's already there

    kdump's dump_to_rootfs will try to start initqueue unconditionally.
    dump_to_rootfs will run after systemd isolate to emergency
    target, so this is currently accetable.

    But there is a problem when initqueue starts the emergency action
    because of initqueue timeout. dump_to_rootfs will start initqueue and
    lead to timeout again.

    So following patch will remove the previous isolation wrapper, and
    detect the service status here. Previous isolation makes the detection
    impossible. Now this detection will be valid and helpful to prevent
    double timeout or hang.
