[pve-devel] [PATCH qemu-server] vzdump: assemble: improve error messages

[Fiona Ebner <f.ebner@proxmox.com>]

by including the errno. Might make it clearer what the issue is in
cases like: https://forum.proxmox.com/threads/135261/

Also add the missing newlines, the missing "to" in the second message,
switch to the more common "or die" and avoid line bloat while at it.
