Bug 1661

I got this error compiling with -Wall -Werror:

../src/network/utils/ipv6-address.cc: In function ‘uint32_t ns3::lookuphash(unsigned char*, uint32_t, uint32_t)’:
../src/network/utils/ipv6-address.cc:64:26: error: typedef ‘ub1’ locally defined but not used [-Werror=unused-local-typedefs]

My version of GCC is 4.8.0 20130411. A trivial patch is here:
