If we're in the error path failing links and we have a link that has grabbed a reference to the fs_struct, then we cannot safely drop our reference to the table if we already hold the completion lock. This adds a hardirq dependency to the fs_struct->lock, which it currently doesn't have. Defer the final cleanup and free of such requests to avoid adding this dependency.
