staging: gpib: mark HP82341 driver as broken

The hp82341 driver uses the isapnp_read_byte() call, but it's not
exported for modules at this point in time:

ERROR: modpost: "isapnp_read_byte" [drivers/staging/gpib/hp_82341/hp_82341.ko] undefined!

So mark it as broken for now, it can be fixed and cleaned up later.
