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.

	  filesystem; while there will be some performance gains from

	  the delayed allocation and inode table readahead, the best

	  table readahead, the best performance gains require enabling ext4

	  features in the filesystem using tune2fs, or formatting a new

	  of ext4 features, the on disk filesystem format stays fully backward

	  compatible.
