In `l3fwd` 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.
