    mm: disable CONFIG_PER_VMA_LOCK until its fixed

    A memory corruption was reported in [1] with bisection pointing to the
    patch [2] enabling per-VMA locks for x86.  Disable per-VMA locks config to
    prevent this issue until the fix is confirmed.  This is expected to be a
    temporary measure.
