Subject: [PATCH] reiserfs: Delete an unnecessary check before brelse()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 3 Sep 2019 20:00:16 +0200

The brelse() function tests whether its argument is NULL
and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
