[qca-nss-ecm] Fix for OVS flow query and CI defunct

ECM connection instances (CI) are created through POSTROUTE Hook for
OVS route flows. When netfilter CT expires or CI expires, OVS route flow rules
are deleted.
This patch removes CI deletions through OVS flow delete notifier when OVS flow
rule is routed.
This patch fixes endianness for TCP/UDP port numbers(network byte order).
