When shrinking a filesystem, resize2fs wants to free per-bg metadata
blocks that are no longer needed. This behavior is gated on whether
there's a superblock in the group as told by new_fs. The check really
should be against old_fs, since we're effectively freeing blocks out
of old_fs in the transition to new_fs, but prior to sparse_super2 this
didn't matter since superblocks didn't move, so it didn't matter.
Under sparse_super2, however, there's a superblock in the last group,
so now we need to change the test to use old_fs as it should.
