This error was discovered by fuzzing qemu-img. This commit fixes a division by zero error in the bench_cb() function that occurs when using the bench command with a zero-sized image. The issue arises because b->image_size can be zero, leading to a division by zero in the modulo operation (b->offset %= b->image_size). This patch adds a check for b->image_size == 0 and resets b->offset to 0 in such cases, preventing the error. Signed-off-by:
