[dts][PATCH V1 4/6] tests/dpdk_gro_lib_cbdma: delete modify dpdk code by dpdk change

[Wei Ling <weix.ling@intel.com>]

According to the dpdk commit 1945c64674(app/testpmd: perform SW IP
checksum for GRO/GSO packets) and commit 8ba1723783(net/vhost:
perform SW checksum in Tx path), no need to modify DPDK code to test.
