[c-nsp] changing the number of equal-cost paths

The packet loss would be very very minimal. Users most likely will
not even notice it.

Your biggest worry in these environments is the hw programming
resources and memory usage when you go with so many dual paths.
Just be aware of that and make sure your hw programming LC's
can support it.
