[PATCH 2/4] reiserfs: centralize freeing of reiserfs info

[Christian Brauner <brauner@kernel.org>]

Currently the reiserfs info is free in multiple locations:

* in reiserfs_fill_super() if reiserfs_fill_super() fails
* in reiserfs_put_super() when reiserfs is shut down and
  reiserfs_fill_super() had succeeded

Stop duplicating this logic and always free reiserfs info in
reiserfs_kill_sb().
