[Qemu-devel] [PATCH 1/1] qemu-img: wait for convert coroutines to complete

["Denis V. Lunev" <den@openvz.org>]

From: Anton Nefedov <anton.nefedov@virtuozzo.com>

We should wait for other coroutines on error path, i.e. one of coroutines
terminates with i/o error, before cleaning the common structures. In the
other case we would crash in a lot of different places. This behaviour
was introduced by commit 2d9187bc65.
