drm/i915: Fix oops due to missing stack depot
We call __save_depot_stack() unconditionally so the stack depot
must always be initialized or else we'll oops on platforms without
runtime pm support.
Presumably we've not seen this in CI due to stack_depot_init()
already getting called via drm_mm_init()+CONFIG_DRM_DEBUG_MM.
