qemu-pr-helper -v suppresses errors, isn't that weird?

[Markus Armbruster <armbru@redhat.com>]

prh_co_entry() reports reports errors reading requests / writing
responses only when @verbose (command line -v); relevant code appended
for you convenience.

Sure these are *errors*?  The program recovers and continues, and this
is deemed normal enough to inform the user only when he specifically
asks for it.  Yet when we inform, we format it as an error.  Should we
tune it down to warnings?


static void coroutine_fn prh_co_entry(void *opaque)
{
    [...]
    while (atomic_read(&state) == RUNNING) {
        [...]
        sz = prh_read_request(client, &req, &resp, &local_err);
        if (sz < 0) {
            break;
        }
        [...]
        if (prh_write_response(client, &req, &resp, &local_err) < 0) {
            break;
        }
    }
    if (local_err) {
        if (verbose == 0) {
            error_free(local_err);
        } else {
            error_report_err(local_err);
        }
    }

out:
    qio_channel_detach_aio_context(QIO_CHANNEL(client->ioc));
    object_unref(OBJECT(client->ioc));
    g_free(client);
