vpc images are created with bigger virtual size than required
Description of problem:
Required virtual size is 895287296, but as qemu-img info reports it is 895426560.
Steps to reproduce:
1. qemu-img create -f vpc img1.vpc 895287296
2. qemu-img info img1.vpc
Additional information:
Converting back and forth is not possible as a result
```
$ qemu-img info openSUSE-Leap-15.3-GNOME-Live-x86_64-Media.iso
image: openSUSE-Leap-15.3-GNOME-Live-x86_64-Media.iso
file format: raw
virtual size: 854 MiB (895287296 bytes)
disk size: 854 MiB
$ qemu-img create -f vpc img1.vpc 895287296
Formatting 'img1.vpc', fmt=vpc size=895287296
$ qemu-img convert -n \
-f raw openSUSE-Leap-15.3-GNOME-Live-x86_64-Media.iso \
-O vpc img1.vpc
$ qemu-img compare \
-f raw openSUSE-Leap-15.3-GNOME-Live-x86_64-Media.iso \
-F vpc img1.vpc
Warning: Image size mismatch!
Images are identical.
$ qemu-img create -f raw img2.raw 895287296
Formatting 'img2.raw', fmt=raw size=895287296
$ qemu-img convert -n -f vpc img1.vpc -O raw img2.raw
qemu-img: output file is smaller than input file
$ qemu-img compare \
-f raw openSUSE-Leap-15.3-GNOME-Live-x86_64-Media.iso \
-F raw img2.raw
Content mismatch at offset 0!
