[PATCH v2 14/14] btrfs-progs: image: Fix error output to show correct return value

[WenRuo Qu <wqu@suse.com>]

We can easily get confusing error message like:
  ERROR: restore failed: Success

This is caused by wrong "%m" usage, as we normally use ret to indicate
error, without populating errno.

This patch will fix it by output the return value directly as normally
we have extra error message to show more meaning message than the return
value.
