[dpdk-dev] [PATCH v1] examples/ip_pipeline: fix build issue with GCC 13

[<jerinj@marvell.com>]

From: Jerin Jacob <jerinj@marvell.com>

Fix the following build issue by initializing req to NULL for
the local variable.

In function 'thread_msg_handle', inlined from 'thread_main' at
../examples/ip_pipeline/thread.c:3130:6:
../examples/ip_pipeline/thread.c:535:20: warning: 'req' may be used
uninitialized [-Wmaybe-uninitialized]
  535 |                 if (req == NULL)
      |                    ^
../examples/ip_pipeline/thread.c: In function 'thread_main':
../examples/ip_pipeline/thread.c:433:32: note: 'req' was declared here
  433 |         struct thread_msg_req *req;
