Subject: [PATCH 13/19] qemu-img: fix img_compare() flags error path

O-Subject: [RHEL-7.1 qemu-kvm PATCH v2 5/4] qemu-img: fix img_compare() flags error path
Bugzilla: 1138691
RH-Acked-by: Kevin Wolf <kwolf@redhat.com>

From: Stefan Hajnoczi <stefanha@redhat.com>

If img_compare() fails to parse the cache flags the goto out3 code path
will call qemu_progress_end().  Make sure we actually call
qemu_progress_init() first.
