Subject: [PATCH] staging: comedi: gsc_hpdi: 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 async command support. Tidy
up the factored out code.

To minimize the noise, change the dev_err() to dev_dbg().
