of: reserved_mem: add missing of_node_put() for proper ref-counting

Browse source 
Commit d698a38814 ("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: d698a38814 ("of: reserved-memory: ignore disabled memory-region nodes")
