mediatek: mt76: mac80211: Fix missing of_node_put() in mt76_led_init()

Browse Source 
[ Upstream commit 0a14c1d0113f121151edf34333cdf212dd209190 ]

We should use of_node_put() for the reference 'np' returned by
of_get_child_by_name() which will increase the refcount.

Fixes: 17f1de56df ("mt76: add common code shared between multiple chipsets")
