examples: fix queue ID restriction

Currently application supports Rx queue IDs up to 255
and max queues of 256 irrespective of device support.
This limits the number of active lcores to 256.

The patch fixes these constraints by increasing
the Rx queue IDs to support up to 65535.

Fixes: af75078fece3 ("first public release")
Fixes: f88e7c175a68 ("examples/l3fwd-power: add high/regular perf cores options")
Fixes: 08bd1a174461 ("examples/l3fwd-graph: add graph-based l3fwd skeleton")
