iLO5 drives duplicates

[motasuwa]

Hi Team, thanks for the exporter,

Scraping the iLO5 server script completes GET requests for each drive correctly and receives the response successfully, however label 'Location' is parsed incorrectly, thus the label is empty and since there are no other differences in labels between drives, the metrics are deduplicated and missed.

Example how it works incorrectly with iLO5:

Example how it works correctly with iLO4:

Thanks!
