In `l3fwd-graph` application, Tx queues are configured per lcore
to enable a lockless design and achieve optimal performance.
The `MAX_TX_QUEUE_PER_PORT` macro, defined as `RTE_MAX_ETHPORTS`,
introduced an artificial constraint on the number of Tx queues
and limited core-scaling performance.
This patch removes the unused `MAX_TX_QUEUE_PER_PORT` macro and
redundant Tx queue check, allowing Tx queues to scale directly
with the no. of lcores.
