A prior patch [1] (applied as "app/testpmd: fix copy of raw flow item"), addresses a crash in testpmd's flow copy function. The first patch of the present series [2] addresses remaining issues with its behavior which is, in fact, what caused the original issue. While both patches focus on testpmd, rte_flow also exposes its own public copy function with the exact same code that breaks when encountering a RAW pattern item. Primary users for this function are bonding and failsafe PMDs. This patch therefore addresses both [1] and [2] at once for rte_flow_copy().
