staging: comedi: pcmuio: tidy up pcmuio_handle_asic_interrupt()

Unfortunatly, since there could be two asics, we can't use dev->read_subdev
to get the subdevice. But, the comedi_subdevice associated with the 'asic'
can easily be calculated. This allows removing the for () loop that searched
for the correct subdevice.

Tidy up the function.
