Subject: [PATCH] comedi: don't build module device_ids if built in

If not building as a module, then the device_ids[] array is not used
by the  MODULE_DEVICE_TABLE(pnp, device_ids) so remove the warning
about it not being used by enclosing it in #ifdef MODULE

Fixes:

drivers/comedi/drivers/ni_atmio.c:209:35: warning: ‘device_ids’ defined but not used [-Wunused-const-variable=]
