mtd: partitions: Fix refcount leak in parse_redboot_of

[ Upstream commit 9f7e62815cf3cbbcb1b8cb21649fb4dfdb3aa016 ]

of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: 237960880960 ("mtd: partitions: redboot: seek fis-index-block in the right node")
