    xl: initialise rc before using it in vcpuset
    
    In 5b725e56 (xl: improve return and exit codes of vcpu related
    functions), the return value of libxl_cpu_bitmap_alloc was not stored in
    rc anymore. Yet the subsequent fprintf still used that.
    
    Reinstate the original implementation, that is, to store return value of
    libxl_cpu_bitmap_alloc in rc before using rc.
