- Deprecate 'rte_malloc', use 'rte_mempool_get' for inserting UOA instead.
- Remove unnecessary reference counting for 'struct inet_device'.

Codes are OK now. But mempool of the same size with dp_vs_conn may not memory friendly enough.
Actually, we are planning to fix rte_malloc problem in all critical packet pathes using dpvs's mempool， which supports variable length mempool and provides a balance between rte_malloc and dpdk mempool.You could help us with the plan if you are interested with it.

for now, struct conn_uoa has 6 bytes only, maybe use prot_data directly
uoa = (void*)&(*conn)->prot_data
