drm: adv7511: Fix use-after-free in adv7533_attach_dsi()
commit 81adbd3ff21c1182e06aa02c6be0bfd9ea02d8e8 upstream.
The host_node pointer was assigned and freed in adv7533_parse_dt(), and
later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue
by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()
in error path of probe() and also in the remove().
