staging: comedi: adv_pci1710: only init async command members when needed

Browse source

The 'len_chanlist' and 'cancel' members of the comedi_subdevice are
only used with async command support. Only initialize them if the irq
was sucessfully requested.

Also, only init the dev->read_subdev if we have the irq.
