    x86: cpu -- Proceed even if xsavec detected for dev reason
    
    Andrew reported that previously he been able to c/r even
    on the machine with xsavec enabled, so allow to process
    for now.
    
    P.S.I'm investigating the problem and to not block testing
    process lets permit passing with xsaves bit present.
