Commit e39e959e fixed an invalid assertion in the .bdrv_length implementation, but left a similar assertion in place for .bdrv_truncate. Instead of crashing when the user requests a too large image size, fail gracefully. A file size of exactly INT64_MAX caused failure before, but is actually legal.
