staging: comedi: pcl3730: use comedi_request_region()

Use comedi_request_region() to request the I/O region used by this
driver.

Remove the noise when the board is first attached as well as the
error message when the request_region() fails, comedi_request_reqion()
will output the error message if necessary.

Also, remove the unnecessary 'dev->irq = 0'. This driver does not
use interrupts and the comedi core has already cleared this variable.
