[PATCH v2 3/5] examples/ip_fragmentation: remove redundant Tx queue limit

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

In `ip_fragmentation` 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.
