[dpdk-dev,v3,1/5] librte_table: fix acl entry add and delete functions

  The rte_table_acl_entry_add() function was returning data from
acl_memory instead of acl_rule_memory. It was also returning data
from entry instead of entry_ptr.

The rte_table_acl_entry_delete() function was returning data from
acl_memory instead of acl_rule_memory.

Fixes: 166923eb2f78 ("table: ACL")

Why not use rte_memcpy instead?.
