Initialize sin6_scope_id to zero

sin6_scope_id is not explicitly set to zero in tcp_input() which should be OK
for global IPv6 addresses, but seems to fail on Mac OS: if sin6_scope_id ends up
with a value other than zero for global addresses, connect() will fail with "No
route to host".
Tested on Mac OS v11.5.2 but might be an issue on other versions as well.
