powerpc/pseries: Fix parent_dn reference leak in add_dt_node()
commit b537ca6fede69a281dc524983e5e633d79a10a08 upstream.
A reference to the parent device node is held by add_dt_node() for the
node to be added. If the call to dlpar_configure_connector() fails
add_dt_node() returns ENOENT and that reference is not freed.
Add a call to of_node_put(parent_dn) prior to bailing out after a
failed dlpar_configure_connector() call.
Fixes: 8d5ff320766f ("powerpc/pseries: Make dlpar_configure_connector parent node aware")
