[Qemu-block] [PATCH v3 2/4] qemu-img: fix --image-opts usage with dd com

From: Daniel P. Berrange
Subject: [Qemu-block] [PATCH v3 2/4] qemu-img: fix --image-opts usage with dd command
Date: Mon, 20 Feb 2017 15:19:19 +0000

The --image-opts flag can only be used to affect the parsing
of the source image. The target image has to be specified in
the traditional style regardless, since it needs to be passed
to the bdrv_create() API which does not support the new style
