qemu-img: fix division by zero in bench_cb() for zero-sized images
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.
