cleanup: libsqfs: eliminate block writer statistics

 - the "bytes submitted" can be moved over to the block processor
 - the number of blocks submitted are already there (implcitily, by
   adding the data block count to the fragment block count)
 - actual data bytes written can be computed from the super block
 - the remaining block count can be changed to simple counter that
   can be obtained through a function.
