logfs: destroy the reserved inodes while unmounting
We were assuming that the evict_inode() would never be called on
reserved inodes. However, (after the commit 8e22c1a4e logfs: get rid
of magical inodes) while unmounting the file system, in put_super, we
call iput() on all of the reserved inodes.
The following simple test used to cause a kernel panic on LogFS:
1. Mount a LogFS file system on /mnt
2. Create a file
$ touch /mnt/a
3. Try to unmount the FS
$ umount /mnt
The simple fix would be to drop the assumption and properly destroy
the reserved inodes.
