[ndnSIM] a bug in the ndnSIM source code

[Alex Afanasyev]

Hi guys,

This specific problem doesn't seem to be boost-related.  It is just new compilers are more verbose in reporting various harmless warnings and they are treated (unless CXXFLAGS is overriden) as errors in NS-3.

I have used Zongyi's suggestion and commented out those unnecessary variables (applied in commit c837263e082983a28d4b695d577fedf5ac7707ef).
