Subject: [PATCH 1/2] block-rbd: Delete an unnecessary check before the
 function call "rbd_dev_destroy"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 23 Nov 2015 20:16:45 +0100

The rbd_dev_destroy() 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.
