Resize rbd image to size -1 allows rbd image to be resized to 15 Exabytes, which is incorrect.
Expecting it to throw error message "size cannot take a negative value".

Pasting below the screen shot for reference.

ubuntu@burnupi64:~/qemu/qemu$ rbd resize rbd/rbd1 --size -1
Resizing image: 100% complete...done.
