fdt_num_mem_rsv() and fdt_get_mem_rsv() currently don't sanity check their parameters, or the memory reserve section offset in the header. That means that on a corrupted blob they could access outside of the range of memory that they should. This improves their safety checking, meaning they shouldn't access outside the blob's bounds, even if its contents are badly corrupted.
