i2c: core: decrease reference count of device node in i2c_unregister_device

Browse source

commit e0638fa400 upstream.

Reference count of device node was increased in of_i2c_register_device,
but without decreasing it in i2c_unregister_device. Then the added
device node will never be released. Fix this by adding the of_node_put.
