Subject: [PATCH 05/10] dm snapshot: Delete unnecessary variable
 initialisations in pending_complete()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 29 Sep 2016 08:25:47 +0200

Three local variables will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation at the beginning.
