    Stop calling multipath -r when attaching/detaching iSCSI volumes

    Looking into this more there isn't any documented reason why we do this,
    and on Ubuntu 16.04 there are issues with timing and devices/symlinks
    getting messed up when we do the reload of device maps. We shouldn't
    need to be forcing multipathd to do this, it loads devices on its own.

    We'll leave in the one in 'wait_for_rw(..)' for now because there is
    some evidence that you may need to call it to update the rw state of
    the multipath devices, see:
