xbzk 5239cbe2a7 [nce] handles duplicate NCE interrupts (#4530)

-------------------
Another crash observed in Ender Magnolia: A deadlock caused between CPUCore_0/GPU/GPUFencingThread.

CPUCore_0 waits for GPU work inside the NCE fault handler
GPU waits for the syncpoint mutex
GPUFencingThread holds that mutex while waiting for CPUCore_0 NCE interrupt lock

The fix makes duplicate interrupts return before acquiring the lock, while the first request keeps its original behavior.
