[dts] [PATCH V2] tests/ddp_mpls: test-pmd add parameter --disable-rss

[xiewei]

iavf has rss hash rx offload capability by default, but i40evf not have.
So the hash value and rx queue number will be random when receive wrong label MPLS packets.
If want to wrong label packets received by default queue 0, just launch test-pmd with parameter "--disable-rss".

v2: re-launch testpmd is a waste of time, and start testpmd with 'disable-rss` directly.

v1: compatible with iavf and i40evf for vf.
