[PATCH] src: netlink_delinearize: Fix datatype for len

[Shivani Bhardwaj <shivanib134@gmail.com>]

Change the data type of len from unsigned int to int in order to make
it valid for checks like

if (len < 0)

The issue was brought into attention by the unexplained behavior of
frag with frag-off. Bugzilla entry:
https://bugzilla.netfilter.org/show_bug.cgi?id=935

This patch fixes this bug, however there are still issues with frag
that need to be fixed.
