tcp: fix the tcp src-address cli
When the src-address to add match a route without a valid output interface(such as default route 0.0.0.0/0), fib_entry_get_resolving_interface() will return (u32)~0, which will cause crash in ip4_neighbor_proxy_enable(). Type: fix Signed-off-by: Mercury <mercury124185@gmail.com> Change-Id: I5aee5676a2ff43ec06745ebed4dba2b9e5b98c4d
