as comedi_alloc_subdevices may fail, we leak out the memory allocated by alloc_private,
and also the I/O regions we requested.

free out the private data pointer of the driver, and release the I/O regions.

This breaks the build.

Also Hartley and Ian, what's the point of alloc_private()? It's
just hiding stuff which we need to know about and use later on

Granted, it was more useful before we got kzalloc()!
