    xen: sched: use default scheduler upon an invalid "sched="
    
    instead of just the first scheduler we find in the array.
    
    In fact, right now, if someone makes a typo when passing
    the "sched=" command line option to Xen, we (with all
    schedulers configured in) pick ARINC653, which is most
    likely not what one would expect.
    
    Go for the default scheduler instead.
