Subject: [PATCH v2] staging/comedi: Remove if(); statement without effect

Smatch warns about:
staging/comedi/drivers/cb_pcidas64.c:3304 prep_ao_dma() warn: if();

So the check currently does nothing and can be removed, as indicated by
Ian.

v1 was staging/comedi: Fix if(); by adding proper code
which was unfortunately wrong.
