qdev_init_bdrv() expects that each drive added is the next logical unit for
the given interface type. However, when dealing with hotplug, there may
be holes in the units. drive_init reclaims holes in units but qdev_init_bdrv()
is not smart enough to do this.
Oh, right.
Suggestions for a less ugly solution are appreciated.
See attached patch. Isn't exactly pretty. But at least it is less
invasive and IMHO the logic is easier to understand as well.
Warning: *untested*.
