tcp: fix endpoint lookup failed caused by key uninitialized

fix ipv4 key uninitialized in local_endpoints_table,
which will cause transport_endpoint_cleanup() failed
to lookup the endpoint and can not delete it,
as for ipv6, clib_memcpy_fast() will change all bytes of lcl_addr
and there maybe no need to initalize,

Type: fix
