staging: comedi: fixing coding style problems

This patch fixes warnings of checkpatch.pl script:

CHECK:UNNECESSARY_PARENTHESES: Unnecessary parentheses around devpriv->timer
+        init_timer(&(devpriv->timer));

CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis
+        dev_info(dev->class_dev,
+                "%s: %i microvolt, %li microsecond waveform attached\n",

Task of Eudyptula challenge.
