of: reserved_mem: print skipped node name when too many regions are defined

When too many reserved memory regions are defined,
fdt_init_reserved_mem_node() logs an error and skips the region without
naming the node.

Print the node name so the skipped node can be identified, matching
fdt_scan_reserved_mem().
