Image locking errors happening at device initialization time doesn't say which file cannot be locked, for instance, -device scsi-disk,drive=drive-1: Failed to get shared "write" lock Is another process using the image? could refer to either the overlay image or its backing image. Hoist the error_append_hint to the caller of raw_check_lock_bytes where file name is known, and include it in the error hint.
