Sample values in comedi are generally represented as unsigned values.
Change the `ao_data[]` and `dmabuf_virt[]` members of `struct
pci9118_private` and various local variables dealing with sample values
to use `unsigned short` instead of `short` for consistency.
Also remove the `short *ai_data` member of `struct pci9118_private` as
it is only assigned to.

Nit. Is the cast really needed?
Yes, because __get_free_pages() returns unsigned long, not a void *.
