staging: gpib: convert comments from // to /* */

This patch converts some comments from // -> /* */ to make everything consistent as suggested
in the TODO file in drivers/staging/gpib/TODO

This patch only updates part of the driver to keep a reasonable patch size. Further conversions
will be submitted in follow-up patches if this is accepted.
