Btrfs: fix error handling in btrfs_get_sb
If we failed to find the root subvol id, or the subvol=<name>, we would
deactivate the locked super and close the devices. The problem is at this point
we have gotten the SB all setup, which includes setting super_operations, so
when we'd deactiveate the super, we'd do a close_ctree() which closes the
devices, so we'd end up closing the devices twice. So if you do something like
this
mount /dev/sda1 /mnt/test1
mount /dev/sda1 /mnt/test2 -o subvol=xxx
umount /mnt/test1
it would blow up (if subvol xxx doesn't exist). This patch fixes that problem.
Thanks,
