examples/l3fwd-acl: fix possible memory leak

At error app_acl_init() can return without freeing dynamically allocated memory.
Not really a big problem, as if app_acl_init() fails,
then application would terminate immediately anyway.
Though it is a good coding practise to make a function to cleanup after itself.
