tcp: add more specific possible drop reasons in tcp_rcv_synsent_state_process()

This patch does two things:
1) add two more new reasons
2) only change the return value(1) to various drop reason values
for the future use

For now, we still cannot trace those two reasons. We'll implement the full
function in the subsequent patch in this series.
