[dpdk-dev] [PATCH v2] examples/ip_pipeline: fix buffer not null terminated

[Jasvinder Singh]

The destination string may not have a null termination if
the source string's length is equal to the sizeof(pipeline->name).

Fix by replacing strncpy with strlcpy that guarantees NULL-termination.

Coverty issue: 272606
Fixes: d75c371e9b46 ("examples/ip_pipeline: add pipeline object")
