Fix a (long standing?) bug in ip_output(): if ip_insertoptions() is
called and ip_output() encounters an error and bails (i.e. host unreachable), we will leak an mbuf. This is because the code calls m_freem(m0) after jumping to the bad: label at the end of the function, when it should be calling m_freem(m). (m0 is the original mbuf list _without_ the options mbuf prepended.) Obtained from: NetBSD
