firewire: warn on unfinished transactions during card removal
After card->done and card->work are completed, any remaining pending request would be a bug. We cannot safely complete a transaction at that point anymore. IOW card users must not drop their last fw_card reference (usually indirect references through fw_device references) before their last outbound transaction through that card was finished.
