[PATCH] btrfs/219: fix problems with mount old generation

["Flint.Wang" <hmsjwzb@zoho.com>]

Hi Nikolay & David,

As we discussed, I changed the test btrfs/219 to make it pass.

This test try to mount btrfs filesystem with old generation.

Devices are matched by UUID in btrfs filesystem. The mount of btrfs with
old generation should be failed on purpose.
