[PATCH 1/4] ASN.1: Adjust two function calls together with a variable assignment

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 10 Nov 2017 10:40:17 +0100

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code places.
