    Revert "VMware: fix race for datastore directory existence"

    This reverts commit 743b74d59d3279478c512a0a559642b1d05284bc,
    which introduces a race condition when creating the initial
    instance image. Since _mkdir() no longer fails if the directory
    exists, two computes racing to create the same image will
    result in either corrupted data, lost data, or a strange
    failure later on.
