of/fdt: Don't copy garbage after "/" in root node path
The root node path must be internally converted to "/", or various pieces of code looking for it that way will fail. The code to do that however had a bug where we might incorrectly append pieces of the original path from the fdt to the "/". We should probably add a proper dedicated accessor for the root node but in the meantime this patch should fix it.
