[PATCH] doc: fix filesystems/porting.rst whitespace

If we start with spaces instead of tabs, rst seems to get confused and
italicize some things (presumably because of the `*'s).

Instead, let's switch to using leading tabs as we do elsewhere in the file.

iget4() and the read_inode2 callback have been superseded by iget5_locked()
which has the following prototype::

- struct inode *iget5_locked(struct super_block *sb, unsigned long ino,
- int (*test)(struct inode *, void *),

'test' is an additional function that can be used when the inode
number is not sufficient to identify the actual file object. 'set'
