staging: gpib: Change error code for no listener

Browse source

When doing a write a test is made to see whether there are any
listeners. The code was returning ENODEV which is incorrect.
The user library translates ENOTCONN to a user level no listener
error code.

Change the error code to ENOTCONN.
