Subject: [PATCH] staging: comedi: pass subdevice to comedi_buf_reset()

Change the parameters of `comedi_buf_reset()` 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.
