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 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.

 	  module will be called ext4.
