hurd: Fix restoring message to be retried
save_data stores the start of the original message to be retried,
overwritten by the EINTR reply. In 64b builds the overwrite is however
rounded up to the 64b pointer size, so we have to save more than just
the 32b err.
Thanks a lot to Luca Dariz for the investigation!
