fdt_num_mem_rsv() can return an error if the memory reservation block is not properly terminated with a (0, 0) entry. However several other places in libfdt called it without checking for error returns, and could therefore return strange results, or in the case of fdt_open_into() crash. Fix this by always checking the return value. Add some addition tests to catch this bug.
