[pbs-devel] [PATCH proxmox-backup] pbs-client: print error when we couldn't download previous fidx/didx

[Dominik Csapak <d.csapak@proxmox.com>]

When we have a previous manifest, we try to download the fidx/didx files
to get the known chunks list. We continue if that fails (which is ok),
but we did not print any error, leading to a confusing backup output,
since the users would expect that chunks will be reused.

Printing the error should at least make it apparent that something did
not work correctly.

i sent it with 'eprintln' instead of the log macro, since that series
was not applied yet. i'll happily resend it when thats done with the log
macro, or i can send it now but i guess then hannes patches will not
apply anymore since i'd have to add the log dependency myself
