usb: musb: Fix missing of_node_put() in omap2430_probe

Browse Source 
[ Upstream commit 424bef51fa ]

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

Fixes: 8934d3e4d0 ("usb: musb: omap2430: Don't use omap_get_control_dev()")
