[PATCH v1] drm/xe: avoid the async_flip update in the initial plane config

Async flip call is not needed. The updated fb mapping is updated
as part of the fixup_initial_plane_config() call. Otherwise we
end up updating the PLAN_SURF register twice with the same info.

v2: avoid async_flip instead of removing fixup call (Ville)
