fix(zfcp_rules): use the right wwpn and lun vars and support new devi…

…ce format

Commit c8e5312 introduced a regression that
causes the parsed `_wwpn` and `_lun` from SCSI device nodes to not be passed
to the `create_udev_rule` function.

Also, the format of these udev-created SCSI device nodes has changed, now it
looks like: `ccw-<device_bus_id>-fc-<wwpn>-lun-<lun>-part<n>`

Fixes c8e5312
