If you take out the fix, some tests will fail:

FAIL: ix86 EVEX no disp scaling
FAIL: x86-64 EVEX no disp scaling

commit 629cfaf1b0fbb32a985607c774bd8e7870b9fa94

    x86: don't mistakenly scale non-8-bit displacements

    In commit b5014f7af2 I've removed (instead of replaced) a conditional,
    resulting in addressing forms not allowing 8-bit displacements to now
    get their displacements scaled under certain circumstances. Re-add the
    missing conditional.
