staging: gpib: fluke console messaging cleanup

Enable module name to be printed in pr_xxx and dev_xxx
Use DRV_NAME defined as KBUILD_MODNAME instead of hard coded
string "fluke_gpib" in platform_driver struct.

Remove commented printk's.

Change pr_err to dev_err wherever possible

Remove "fluke_gpib:" prefix in messages since this is
printed with the module name.

Correct dev_err message erroneously containing cb7210 identifier.
