src: Creating faces to neighbors explicitly by NLSR

Nlsr creates faces to all neighbors explicitly like nfdc create faces.
After successful creation of all faces Nlsr will proceed for further
processing. In case of failure in creating any face, Nlsr will exit
immediately by destroying the created faces.
