    journal: fix invalid format string in warning
    
    Remove the erroneous extra string format specifier ('%s') that was
    not passed; which of course is a bug and made some architectures
    fall over. Should never actually happen in the wild, because bolt
    tries very hard to not write invalid journal entries ... but who
    knows.
