[PATCH] ext4: correct comment references to ext4_ext_direct_IO()

[PATCH] ext4: correct comment references to ext4_ext_direct_IO()

[Eric Whitney]

Commit 914f82a32d0268847 "ext4: refactor direct IO code" deleted
ext4_ext_direct_IO(), but references to that function remain in
comments.  Update them to refer to ext4_direct_IO_write().
