XFS Direct IO, unaligned block zeroing at 128K boundery

[Ajeet Yadav]

Hello,
Its my fault,
Our kernel 2.6.30.9, however we migrated XFS to higher version 2.6.34

We undo the XFS changes from commit 5fe878ae7f82fbf0830dbfaee4c5ca18f3aee442
because our fs/direct_io.c belong to version 2.6.30.9, and we do not want to
change it.
