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.
