    xen: Fix incorrect taint constant
    
    Insecure is the word being looked for here.  Especially given the nature of
    the sole caller, and the (correct) comment next to it.
    
    Also update the taint marker from 'U' to 'I' for consistency; this isn't
    expected to impact anyone in practice.
    
    Fixes: 82c0d3d491cc ("xen: Add an unsecure Taint type")
