[dpdk-stable] [PATCH 1/2] app/testpmd: fix flow rule copy functions

[Matan Azrad]

The corrupted code checks only RAW flow item type special case for
returning its size but doesn't deal with any other flow item type
and returns 0 for all the others.

This bug leaves the flow descriptor empty for non RAW types.

The fix takes the correct size to any regular types from appropriate
array.

The same issue, with a similar fix, is in flow action size method which deals only with
RSS special type.
