    server/smartcard: fix smartcard_channel_send_error
    
    It was sending the wrong data, the memory right after the VCSMsgHeader
    which was actually not where the data was.
    
    Fixed by having the header and data (VSCError, 4 bytes of the error code)
    embedded in the ErrorItem pipe item.
