[PATCH] staging: comedi: db_pcidas64: invert conditional

[Tobin C. Harding]

Checkpatch emits WARNING: Avoid multiple line dereference. It is
possible to reduce the level of indentation by inverting a conditional
and continuing loop if new conditional evaluates to true.

Invert conditional. Continue loop if new conditional evaluates to
true. Reduce subsequent code indentation level by 1. Move multi-line
dereference onto single line.
