[PATCH 7/7] USB-iowarrior: Apply another recommendation from "checkpatch.pl"

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 21 Aug 2016 15:30:11 +0200

The script "checkpatch.pl" can point out that assignments should usually
not be performed within condition checks.
Thus move the assignments for two local variables to separate statements.
