drm/i915/selftests: Do not overwrite error code after intel_context_migrate_clear() call

Browse Source 
Currently this function's error code is stored in err variable,
which, if a i915_request is present, will be immediately
overwritten by return from dma_resv_reserve_fences(). Call DMA
functions only if intel_context_migrate_clear() succeeded.
