[dpdk-dev] [PATCH v2 1/1] example/ip_pipeline: fix memcpy issue

[Piotr Azarewicz <piotrx.t.azarewicz@intel.com>]

The source and destination both are the arrays of cmdline_parse_ctx_t.
So the goal is to copy elements size of cmdline_parse_ctx_t not
cmdline_parse_ctx_t*.

Coverity issue: 120412
Fixes: b4aee0fb9c6d ("examples/ip_pipeline: reconfigure thread binding
dynamically")

Fixes: ea0908c4ab89 ("examples/ip_pipeline: add master pipeline")
Fixes: eb32fe7c5574 ("examples/ip_pipeline: rework initialization parameters")

v2 changes:
- add the same fix in two other places
