Revision 2136 breaks two-disk configuarion

[Pavel Roskin]

Hello!

Since the revision 2136, I'm getting a non-fatal error message:

GRUB loading.
Welcome to GRUB!

alloc magic is broken at 0x7fdaf20
Aborted. Press any key to exit.

After pressing enter, the menu appears and I can boot from it.  The
description of the revision is:

       * disk/fs_uuid.c (grub_fs_uuid_close): Call grub_disk_close()
       on disk->data.

The patch looks wrong to me.  There are no calls to grub_disk_open() in
disk/fs_uuid.c.  Other callers to grub_disk_close() call
grub_disk_open() as well.

# cat /boot/grub/device.map 
(hd0)   /dev/sda
(hd1)   /dev/sdb

The root is on /dev/sdb1.  GRUB is installed on /dev/sda.  Having two
disks is needed to reproduce the problem.
