of: reserved_mem: add missing of_node_put() for proper ref-counting
Commit d698a388146c ("of: reserved-memory: ignore disabled memory-region
nodes") added an early return in of_reserved_mem_device_init_by_idx(), but
didn't call of_node_put() on a device_node whose ref-count was incremented
in the call to of_parse_phandle() preceding the early exit.
Fixes: d698a388146c ("of: reserved-memory: ignore disabled memory-region nodes")
