[PATCH] soundwire: slave: fix an OF node reference leak in soundwire slave device

[Joe Hattori <joe@xxxxxxxxxxxxxxxxxxxxx>]

When initializing a soundwire slave device, an OF node is stored to the
device with refcount incremented. However, the refcount is not
decremented in .release(), thus call of_node_put() in
sdw_slave_release().
