dpdk: fix flow(with mark action) deletion crash issue

Type: fix

this patch fixes mark flow deletion crash issue, see below

test flow add src-ip any proto udp src-port 111 dst-port 222 mark 100
test flow enable index 0 1/1
test flow disable index 0 1/1
test flow enable index 0 1/1
test flow disable index 0 1/1 -> [crash]

This is because the code resets a wrong vector in flow lookup entry
recycle logic. See function dpdk_flow_ops_fn().
