[PATCH] drm/amdkfd: drop warning in event_interrupt_isr_v1*()

Commit ded8b3c36f17 ("drm/amdgpu: properly handle GC vs MM in amdgpu_vmid_mgr_init()")
enables all 16 vmids for MMHUB on GC 10 and newer for KGD since
there are no KFD resources using MMHUB.  With this change, KFD
starts seeing MMHUB vmids in it's range with no pasid set.  As
such there is no need to warn, we can just ignore those interrupts.
