remoteproc: k3-r5: Fix refcount leak in k3r5clusterofinit

Every iteration of foreachavailablechildofnode() decrements the reference count of the previous node. When breaking early from a foreachavailablechildofnode() loop, we need to explicitly call ofnodeput() on the child node. Add missing ofnodeput() to avoid refcount leak.
