ext4: Improve ext4 Kconfig test

Now that ext4 driver must be used to access ext3 filesystems, improve
the Kconfig help text to better explain that using ext4 driver to access
the filesystem is fully compatible with the old ext3 driver.

The ext4 filesystem will support mounting an ext3
filesystem; while there will be some performance gains from
the delayed allocation and inode table readahead, the best
performance gains will require enabling ext4 features in the
filesystem, or formatting a new filesystem as an ext4
filesystem initially.
The ext4 filesystem supports mounting an ext3 filesystem; while there
are some performance gains from the delayed allocation and inode
table readahead, the best performance gains require enabling ext4
features in the filesystem using tune2fs, or formatting a new
filesystem as an ext4 filesystem initially. Without explicit enabling
of ext4 features, the on disk filesystem format stays fully backward
compatible.
To compile this file system support as a module, choose M here. The
module will be called ext4.
