Subject: [PATCH] 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.
