Subject: [PATCH 03/10] dm snapshot: Delete an unnecessary variable
 initialisation in snapshot_map()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 29 Sep 2016 08:00:29 +0200

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