It is possible for our data volume to be attached to a node at a dev
location that we also check for creating swap. However, when we are
attaching a data volume we know we want that volume mounted at the mount
point and not additional swap. Adjust the script to setup the data
volume first then when the make_swap.sh script runs it will see there is
already a filesystem on the device and skip over it.
