drm/amdkfd: potential NULL dereference in kfd_set/reset_event()
If lookup_event_by_id() returns a NULL "ev" pointer then the
spin_lock(&ev->lock) will crash. This was detected by Smatch:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_events.c:644 kfd_set_event()
error: we previously assumed 'ev' could be null (see line 639)
Fixes: 5273e82c5f47 ("drm/amdkfd: Improve concurrency of event handling")
