drm/i915/gem: Flush lmem contents after construction
i915_gem_object_create_lmem_from_data() lacks the flush of the data
written to lmem to ensure the object is marked as dirty and the writes
flushed to the backing store. Once created, we can immediately release
the obj->mm.mapping caching of the vmap.
Fixes: 7acbbc7cf485 ("drm/i915/guc: put all guc objects in lmem when available")
