[Daniel Mrzyglod]

This patch fixes a maybe-uninitialized warning when compiling DPDK with GCC 4.8

examples/ip_pipeline/pipeline/pipeline_common_fe.c: In function 
'app_pipeline_track_pktq_out_to_link':
examples/ip_pipeline/pipeline/pipeline_common_fe.c:66:31: error:
'reader' may be used uninitialized in this function 
[-Werror=maybe-uninitialized]

   struct app_pktq_out_params *pktq_out =

Fixes: 760064838ec0 ("examples/ip_pipeline: link routing output ports to 
devices")
