staging: comedi: pcmuio: tidy up local variables in pcmuio_handle_intr_subdev()

Browse Source 
Tidy up the local variables so that the comedi_cmd is accessed as a pointer
instead of getting to it from the comedi_subdevice pointer.

Remove the local variable 'len' and use the cmd->chanlist_len directly.
