Fix a hardware RTL bug in the TCP XNACK scoreboard reset path on MI300,
where a wave receiving a no-retry FAULT from UTC and subsequently
terminating may leave its scoreboard entry uncleared when reset events
arrive back-to-back.
This can cause a later, unrelated wave using the same scoreboard slot
to incorrectly inherit the XNACK error state, resulting in its VMEM
operations being dropped even though the wave never faulted.
