Remove changing DISK_REF for zfspool mikrotik-routeros.sh (#529)

* Remove changing DISK_REF for zfspool mikrotik-routeros.sh

When running the original script using zfspool as storage I  got the error:

"unable to parse zfs volume name..."

Removing the part that cchnages the DISK_REF is disk is to be located on a zfspool has solved this.

* Fix in live repo
