staging: comedi: pass subdevice to comedi_buf_is_mmapped()
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.
