staging: comedi: amplc_dio200: remove dio200_common_detach()
This exported function just does a free_irq() to release the interrupt handler for the legacy and PCI dio200 drivers. The legacy driver also calls comedi_legacy_detach() which would also do the free_irq(). For that driver the just use comedi_legacy_detach() directly for the (*detach). For the PCI driver, add the free_irq() to the private (*datach) function. Remove the, then unused, dio200_common_detach() function.
