staging: comedi: amplc_pci230: factor out chanlist checking from (*do_cmdtest)

Step 5 of the (*do_cmdtest) validates that the cmd->chanlist is compatible
with the hardware.

For aesthetics, factor out the step 5 code for the analog output and analog
input async command support. Tidy up the factored out code.
