autoconfigure_networking.sh: check device/bus/id for qeth devices

[Marco Pavone]

This is a followup of my comment on patchset 4 of https://review.openstack.org/#/c/439439/:

according to the docs there is only one leading zero. the second digit could still be a separate subchannel set: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Naming_Scheme_for_Network_Devices_Available_for_Linux_on_System_z.html

We need to clarify if DPM takes use of multiple subchannel sets....

More information about subchannel sets (don't mix it up with multiple channel subsystems) can be found here [1], pdf page 46

DPM does not support multiple subchannel sets today. Therefore this bug is invalid. However I will add a comment to the code....
