of/fdt: NULL-terminate the root node path
Commit 509b7455 (of/fdt: Don't copy garbage after "/" in root node path) sets the path length to 0 to ignore any garbage after "/" in the root node path. This has the side effect of also ignoring '\0' at the end of the root node path. This patch sets the ignores the garbage by setting the last character to '\0' and length to 1.
