[PATCH] staging: comedi: comedi_isadma: Use a non-NULL device for DMA API

The "comedi_isadma" module calls `dma_alloc_coherent()` and `dma_free_coherent()` with a NULL device pointer which is no longer allowed. If the `hw_dev` member of the `struct comedi_device` has been set to a valid device, that can be used instead. Unfortunately, all the current users of the
