[PATCH 10/10] md/dm-crypt: Delete unnecessary variable initialisations in crypt_iv_essiv_ctr()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 28 Sep 2016 16:44:32 +0200

Three local variables will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation which became unnecessary with
a previous update step.
