Primary application here kni should initialize packet capture framework using rte_pdump_init(). And uninitialize rte_pdump_uninit() before application terminates. In DPDK by default only testpmd has init/uninit changes added. Rest other application that wants to use pdump should do these changes explicitly, make the build and rerun the primary and dpdk-pdump applications. Please refer app/test-pmd/testpmd.c for rte_pdump* code changes and make similar change in kni main.c and retest. Let me know if you stuck.
