[PATCH] fs/qnx: Delete unnecessary checks before brelse()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 3 Sep 2019 19:15:09 +0200

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

This issue was detected by using the Coccinelle software.
