As blkid manpage mentioned, reading symlink (soft-link) does not
recommend. All will be solved, once we use blkid to get the filesystem
UUID, including the btrfs issue.
Minfei, I did not mean to change the symlink code, instead I talked about
the whole get_presistant_dev function cleanup.
But I will think a bit about this patch, and comment it later.
