fs/reiserfs/: cleanups 



- remove the following no longer used functions:
  - bitmap.c: reiserfs_claim_blocks_to_be_allocated()
  - bitmap.c: reiserfs_release_claimed_blocks()
  - bitmap.c: reiserfs_can_fit_pages()

- make the following functions static:
  - inode.c: restart_transaction()
  - journal.c: reiserfs_async_progress_wait()
