[libnetfilter_log 2/3] Set nflog_errno as needed.

[Eric Leblond <eric@inl.fr>]

Some FIXME were put to fix some issues related to nflog_errno not being set. In both case, this was
related to error treatment of libnfnetlink function. As these functions are setting errno to the
correct value, this patch simply copy errno to nflog_errno in libnetfilter_log.
