staging: gpib: hp_82335: Return error value from gpib_register_driver()

Browse Source 
The function gpib_register_driver() can fail and does not return an
error value if it fails.

Return the error value if gpib_register_driver() fails. Add pr_err()
statement indicating the fail and also the error value.
