[PATCH] test_plans/af_xdp_test_plan: remove tests with pmd_zero_copy arg

[Ciara Loftus <ciara.loftus@intel.com>]

The 'pmd_zero_copy' vdev arg for the AF_XDP PMD was removed in DPDK
v19.11. Remove it from the AF_XDP test plan as it is no longer relevant.
Zero copy is now automatically used if the kernel headers contain the
XDP_UMEM_UNALIGNED_CHUNK_FLAG flag.
