Subject: [PATCH] Revert "qemu-xen-traditional: use O_DIRECT to open disk
 images for IDE"

This reverts commit 1307e42a4b3c1102d75401bc0cffb4eb6c9b7a38.

In fact after a lengthy discussion, we came up with the conclusion
that WRITEBACK is OK for IDE.
See: http://marc.info/?l=xen-devel&m=133311527009773

Therefore revert this which was committed in error.
