30-maas-01-bmc-config: ERROR: Redfish string indices must be integers

[Björn Tillenius]

Got this when running 30-maas-01-bmc-config on a machine that has Redfish info in dmidecode data:

File "/tmp/user_data.sh.HwMzjq/scripts/commissioning/29-maas-01-bmc-config", line 1080, in detect_and_configure
    if bmc.detected():
  File "/tmp/user_data.sh.HwMzjq/scripts/commissioning/29-maas-01-bmc-config", line 1013, in detected
    self._detect()
  File "/tmp/user_data.sh.HwMzjq/scripts/commissioning/29-maas-01-bmc-config", line 995, in _detect
    iface = get_network_interface(fd.read(), vendor_id, product_id)
  File "/tmp/user_data.sh.HwMzjq/scripts/commissioning/29-maas-01-bmc-config", line 1241, in get_network_interface
    if device_type not in machine_resources["resources"]:

ERROR: Redfish string indices must be integers

Note that 29-maas-01-bmc-config is a copy of 30-maas-01-bmc-config that prints out a traceback on errors.
