From 8e9e653038db97bfd343c3fb217b7bf4da765a89 Mon Sep 17 00:00:00 2001
From: Max Reitz <mreitz@redhat.com>

Subject: [PATCH] iotests: Only create BB if necessary

Tests 071 and 081 test giving references in blockdev-add. It is not
necessary to create a BlockBackend here, so omit it.

While at it, fix up some blockdev-add invocations in the vicinity
(s/raw/$IMGFMT/ in 081, drop the format BDS for blkverify's raw child in
071).
