mtd: maps: Fix refcount leak in of_flash_probe_versatile
[ Upstream commit 33ec82a6d2b119938f26e5c8040ed5d92378eb54 ] of_find_matching_node_and_match() 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.
