examples/service_cores: fix lcore count check

Browse Source 
The example has various profiles to run services on specified
number of lcores. Due to incorrect boundary condition, service
can be dispatched to a core that does not exist. This puts main
core into endless wait.

Max available number of service cores is all detected lcores
excluding main core.
