libblkid: remove optimization from verify( funrtion
Now libblkid (the cache based part) tries to probe for the cached
filesystem firstly. This optimization is broken, because:
* new another superblock could be on the device and the original
is already obsolete
* we still need to probe for partitions and raids
* the code was too fragile
The patch also suggests lsblk --fs in blkid.8 for end users. lsblk
read information from used db.
