drm/xe: Fix crash in trace_dma_fence_init()

Browse source 
trace_dma_fence_init() uses dma_fence_ops functions
like get_driver_name() and get_timeline_name() to generate trace
information but the Xe KMD implementation of those functions makes
use of xe_hw_fence_ctx that was being set after dma_fence_init().

So here just inverting the order to fix the crash.
