staging: comedi: drivers: refactor comedi_request_region()
Split comedi_request_region() into two helper functions.
__comedi_request_region()
Handles the actual request_region() call.
comedi_request_region()
Calls __comedi_request_region() and then sets dev->iobase if the
request was successful.
This allows drivers to use the __comedi_request_region() helper
to handle the request without setting the dev->iobase.
