with it in a one-to-one relationship.

All uses of the `subdevice` member of `struct comedi_async` apart from
its initialization have now been removed (by passing around a pointer to
the subdevice instead of to the "async" structure), so get rid of it.

Local function `comedi_buf_munge()` is called by
`comedi_buf_write_free()` to modify (or "munge") the data copied from
a device into the buffer.

Currently, the function takes a pointer to a `struct comedi_async` and
gets a pointer to the comedi subdevice from the `subdevice` member.
Change it to take a pointer to a `struct comedi_subdevice` and get a
pointer to the "async" structure from the `async` member.

The main motivation for this is to elimate the `subdevice` member of
`struct comedi_async`.

Change the parameters of `comedi_buf_is_mmapped()` to pass a pointer to
the comedi subdevice instead of a pointer to the "async" structure
belonging to the subdevice.

The main aim at the moment is to replace all the `struct comedi_async *`
parameters with `struct comedi_subdevice *` parameters in the comedi
driver API.
