The assignment here caused a segfault in test, since there could be pmd
threads referring to the flow when dpcls_remove() is called. We should not

32 UDP flows Spirent test showed no observable improvement but let's
wait for the per-pmd-thread classifier/flow-table~
Otherwise, all tested and looked good~
