net: dpaa: fix device leak when querying time stamp info
commit 3fa840230f534385b34a4f39c8dd313fbe723f05 upstream. Make sure to drop the reference to the ptp device taken by of_find_device_by_node() when querying the time stamping capabilities. Note that holding a reference to the ptp device does not prevent its driver data from going away.
