cxl: Fix refcount leak in cxl_calc_capp_routing
[ Upstream commit 1d09697ff22908ae487fc8c4fbde1811732be523 ]
of_get_next_parent() returns a node pointer with refcount incremented,
we should use of_node_put() on it when not need anymore.
This function only calls of_node_put() in normal path,
missing it in the error path.
Add missing of_node_put() to avoid refcount leak.
Fixes: f24be42aab37 ("cxl: Add psl9 specific code")
