clogd:  Remove scary print statements that show up on --resync
    
    When LVM creates mirrors, it is kind enough to initialize the
    log.  However, when a 'lvchange --resync' is issued to resync
    a mirror, it simply wipes the log instead of reinitializing it.
    The log server was responding to this by issuing a warning that
    it couldn't read a valid log header.  This is not a problem,
    because it simply reinitializes it on its own... so the messages
    served no purpose.
    
    LVM should probably be consistent and initialize the log when
    a --resync is issued though.
