[PATCH] drm/vc4: call ->post_disable() functions in vc4_dsi_encoder_disable()

[Dan Carpenter]

The problem is that the iterator is already at the list head so the
list_for_each_entry_from() loop is a no-op and we don't call the
the iter->funcs->post_disable() functions.  This should be
list_for_each_entry() instead.
