blockdev_init() always creates a DriveInfo, but only drive_new() fills
it in. qmp_blockdev_add() leaves it blank. This results in a drive
with type = IF_IDE, bus = 0, unit = 0. Screwed up in commit ee13ed1c.
Board initialization code looking for IDE drive (0,0) can pick up one
of these bogus drives. Not sure whether getting the QMP command
executed early enough is likely in practice, though.
Fix by creating DriveInfo in drive_new(). Block backends created by
blockdev-add don't get one.
A few places assume a block backend always has a DriveInfo. Fix them
up.
