[CI 3/3] drm/xe: Fix tile fini sequence

[Lucas De Marchi]

From: Matthew Brost <matthew.brost at intel.com>

Only set tile->mmio.regs to NULL if not the root tile in tile_fini. The
root tile mmio regs is setup ealier in MMIO init thus it should be set
to NULL in mmio_fini.

Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")
