The fastmap VID header is embedded in struct ubi_scan_info. During fastmap scan, the header is copied into struct ubi_scan_info, if valid. The former code mixed up the amount of copied bytes and copied more bytes than nessesary. This had no side effect, since the affected struct members are uninitialized at that point and overwritten later. Limit the copied bytes to the VID header size.
