Use the following command:
1. dpdk-testpmd -c 0x3 -n 4 --force-max-simd-bitwidth=64
-- -i --enable-rx-timestamp
2. port stop 0
3. port config 0 rx_offload timestamp off
4. port start 0
Then start it, log will show timestamp info, which should
not appear. Because ice_timestamp_dynflag is still more
than 0, code will still calculate timestamp. So fix it.
