btrfs_wipe_existing_sb() misses calling blkid_do_fullprobe() to do
the real probe. After calling blkid_new_probe() &
blkid_probe_set_device() to setup blkid_probe context, it directly
calls blkid_probe_lookup_value(). This results in
blkid_probe_lookup_value returning -1, because pr->values is empty.
