For comedi subdevices that support asynchronous commands, the `async`
member of `struct comedi_subdevice` points to a `struct comedi_async`
allocated to manage asynchronous commands on that subdevice. The
pointer to this "async" structure is passed around by various functions
and some of those functions need to get back to the "subdevice"
structure from this pointer, so the "async" structure has a `subdevice`
member pointing back to the `struct comedi_subdevice`.
Since we can always get to the "async" structure from the "subdevice"
structure, we can just pass around the pointer to the subdevice instead
of the pointer to the async structure. Then the `subdevice` member of
`struct comedi_async` is no longer required and can be removed.
