    sys/xen: Use __printflike() instead of format(printf)
    
    The __printflike macro sets the format to freebsd_kprintf which recent
    clang understands and warns about. Fixes the following error:
    `passing 'printf' format string where 'freebsd_kprintf' format string is expected [-Werror,-Wformat]`
    
    MFC after:      1 week
    
    (cherry picked from commit 4cd7be3e81863bd22aacccc34fc2e8b2cfcb14d9)
