[dpdk-dev] [PATCH 1/1] ip_pipeline: fix null pointer dereference

[Marcin Kerlin]

Return value of function app_pipeline_type_find is not checking before
dereference. Fix this problem by adding checking condition.

Coverity issue: 127196
Fixes: b4aee0fb9c6d ("examples/ip_pipeline: reconfigure thread binding 
dynamically")
