[PATCH 05/47] block-rbd: One function call less in rbd_dev_image_id() after error detection

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 11 Sep 2016 15:05:49 +0200

The kfree() function was called in one case by the rbd_dev_image_id()
function during error handling even if the passed variable "response"
contained a null pointer.

Adjust a jump target according to the Linux coding style convention.
