[kernel, service] Return ResultSessionClosed when a session is closed (#4318)

-------------------

I tried to run a homebrew game which tried to reply to a closed service. nnSdk expected ResultSessionClosed, we replied with ResultSuccess which mostly works but some have stricter handling and would terminate with abort.
