fs/erofs: Quieten test for filesystem presence

At present listing a partition produces lots of errors about this
filesystem:

   => part list mmc 4
   cannot find valid erofs superblock
   cannot find valid erofs superblock
   cannot read erofs superblock: -5
   [9 more similar lines]

Use debugging rather than errors when unable to find a signature, as is
done with other filesystems.
