blockdev: Don't limit DriveInfo serial to 20 characters
All current users (IDE, SCSI and virtio-blk) happen to share this 20
characters limit. Still, it should be left to device models. They
already enforce their limits. They have to, as the DriveInfo limit
only affects legacy -drive serial=..., not the qdev properties.
usb-storage, which doesn't limit serial number length, also uses
DriveInfo for -usbdevice. But that doesn't provide access to
DriveInfo serial.
