[PATCH rteval 3/4] dmi: check if the dmidecode module is available

[Ralf Ramsauer <ralf.ramsauer@xxxxxxxxxxxxxxxxx>]

Python complained here:
     if not hasattr(dmidecode, 'get_warnings'):
              return

The module dmidecode might not be defined as it is optionally loaded.
Check its existency by checking dmidecode_available.
