util: avoid double close of fd
We could end with a double close if we close the fd loop and flush_fd fails. That would make us goto fail and there we close the fd once again. This patch sets the fd to the return value for safe_close: -1 A fd with negative value will be ignored by the next call to safe_close. CID#996223
