remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init

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