staging: comedi: use refcount in sysfs attribute handlers
Call `comedi_dev_get_from_minor()` instead of `comedi_dev_from_minor()`
in the sysfs attribute handler functions to increment the reference of
the `struct comedi_device` during the operation. Call
`comedi_dev_put()` to decrement the reference afterwards.
