[PATCH 7/9] md/dm-table: Adjust one function call together with a variable assignment

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 1 Oct 2016 08:53:37 +0200

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

ERROR: do not use assignment in if condition

Thus fix the affected source code place.
