Subject: [PATCH 06/10] dm snapshot: Delete an unnecessary variable
 initialisation in snapshot_ctr()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 29 Sep 2016 08:38:29 +0200

The local variable "r" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
