If there are mass of virtblks(exceeding 263), there will be disks
with the same name.
By renaming "sd_format_disk_name()" to "disk_name_format()"
and moving it into block core, virtio_blk can use this function to
support mass of disks.

named vdD-P where both D and P are integers denoting disk number and
partition number? [sh]dX's were created when there weren't supposed
to be too many disks, so we had to come up with the horrible alphabet
based numbering scheme but vd is new enough. I mean, naming is one
thing but who wants to figure out which sequence is or guess what
comes next vdzz9? :(
If we're gonna move it to block layer, let's add big blinking red
comment saying "don't ever use it for any new driver".
format_legacy_disk_name() or something.
