drm/via: Add new condition to via_dma_cleanup()
Pointer dev_priv->mmio, which was checked for NULL at via_do_init_map(),
is passed to via_do_cleanup_map() and is dereferenced there without check.
The patch adds the condition in via_dma_cleanup() which prevents potential NULL
pointer dereference.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 22f579c621e2 ("drm: Add via unichrome support")
