tomd: remove call to update ilo firmware. Two reasons for this:  1) we are not sure it is actually upgrading the firmware  2) sometimes the mco call fails, which aborts the rebuild  3) upgrading the firmware is tangential (at best) to doing a machine     rebuild (we originally included it to assuage a fear of outdated     firmware causing machine rebuild to fail due to outdated APIs)
