i2c: qcom-cci: fix device_node refcount leak in cci_probe()/cci_remove()

The of_node_put() matching of_node_get() runs after i2c_del_adapter(),
whose trailing memset() zeroes adap->dev and thus adap->dev.of_node,
making the put a no-op and leaking the node on every adapter removal
and error cleanup.

Use a devm action: the pointer is captured at registration, out of
reach of that memset(), and devres runs the put once on probe failure
and detach, replacing the three manual of_node_put() calls.  The
setup loop uses the scoped iterator form so the child node is released
automatically if devm_add_action_or_reset() fails mid-loop.
