mtd: parsers: ofpart: Fix refcount leak in bcm4908_partitions_fw_offset
[ Upstream commit e607879b0da18c451de5e91daf239cc2f2f8ff2d ]
of_find_node_by_path() 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.
