staging: gpib: Fix NULL pointer dereference in detach
When the detach function is called after a failed attach
the usb_dev initialization can cause a NULL pointer
dereference. This happens when the usb device is not found
in the attach procedure.
Remove the usb_dev variable and initialization and change the dev
in the dev_info message from the usb_dev to the gpib_dev.
