[PATCH] app/testpmd: fix lcore ID restriction

[Sivaprasad Tummala]

With modern CPUs, it is possible to have higher
CPU count thus we can have higher RTE_MAX_LCORES.
In testpmd application, the current config forwarding
cores option "--nb-cores" is hard limited to 255.

The patch fixes this constraint and also adjusts the lcore
data structure to 32-bit to align with rte lcore APIs.

Fixes: af75078fece3 ("first public release")
