Btrfs-progs: alloc our super copy in btrfs-find-root

Dave fixed the fs_info to allocate the super copy instead of embedding it, but
he failed to notice that I open code open_ctree in btrfs-find-root so we end up
with a super that's not allocated, so we segfault whenever you try to run
btrfs-find-root.  I've fixed this up and now we don't segfault anymore.  Thanks,
