powerpc/cell/axon_msi: Fix refcount leak in setup_msi_msg_address
[ Upstream commit df5d4b616ee76abc97e5bd348e22659c2b095b1c ]
of_get_next_parent() returns a node pointer with refcount incremented,
we should use of_node_put() on it when not need anymore.
Add missing of_node_put() in the error path to avoid refcount leak.
Fixes: ce21b3c9648a ("[CELL] add support for MSI on Axon-based Cell systems")
