[PATCH v6 05/14] examples/l3fwd: fix lcore ID restriction

[Sivaprasad Tummala]

Currently the config option allows lcore IDs up to 255,
irrespective of RTE_MAX_LCORES and needs to be fixed.

The patch fixes these constraints by allowing all
lcore IDs up to RTE_MAX_LCORES.

Fixes: af75078fece3 ("first public release")
