    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.
    (cherry picked from commit effd5676225761abdab90becac519716515c3be4)
