staging: comedi: ni_daq_700: add mux settling delay

commit ffed54dced86723f352323f15789d9ad6bee25e1 upstream.

I got a patch from the original author, Fred Brooks, to add a small
settling delay after setting the AI channel multiplexor.  The lack of
delay resulted in unstable or scrambled data on faster processors.
