drm/amdkfd: Fix TCP XNACK scoreboard reset race
Fix a hardware RTL bug in the TCP XNACK scoreboard reset path 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 slot to incorrectly
inherit the XNACK error state, resulting in its VMEM operations being
dropped even though the wave never faulted.
