[PATCH v3 4/6] examples/ip_reassembly: remove redundant Tx queue limit

[Stephen Hemminger <stephen@networkplumber.org>]

From: Sivaprasad Tummala <sivaprasad.tummala@amd.com>

In `ip_reassembly` 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.

Fixes: cc8f4d020c0b ("examples/ip_reassembly: initial import")
Cc: stable@dpdk.org
