[PATCH v2 2/6] examples/l3fwd-power: fix lcore ID restriction

[Sivaprasad Tummala <sivaprasad.tummala@amd.com>]

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

The patch allows config options based on DPDK config.

Fixes: f88e7c175a68 ("examples/l3fwd-power: add high/regular perf cores options")
