Description of problem:
valgrind is showing a memory leak from  the netlink_init() callpath. Looking at the corresponding netlink-close() method in netcf, it appears it is merely closing the socket, and not free'ing the memory for the libnl handle.

Version-Release number of selected component (if applicable):
0.1.4

How reproducible:
Always

Steps to Reproduce:
1. Run this test program under valgrind

#include <netcf.h>
#include <stdio.h>

int main(int argc, char **argv)
{
    for (int i = 0 ; i < 1000000 ; i++) {
        struct netcf *netcf = NULL;

        ncf_init(&netcf, NULL);

        if (netcf != NULL) {
            ncf_close(netcf);
        }
    }
    return 0;
}


2. Compile and run that as root
