staging: gpib: Remove unnecessary .owner assignment

staging: gpib: Remove unnecessary .owner assignment

The driver core automatically sets the '.owner' field, so there is no
need to assign 'THIS_MODULE' explicitly.

This change fixes the warning reported by the kernel test robot:

cocci warnings: (new ones prefixed by >>)
>> drivers/staging/gpib/eastwood/fluke_gpib.c:1145:3-8: No need to set .owner here. The core will do it.
