OmapiCallbackHandlerVpcd: use appropriate status word to reject MANAGE CHANNEL
ISO/IEC 7816-4 specifies a status word to reject MANAGE CHANNEL instructions
in case the card does not support multiple channels.
Let's also print an error message in the log to simplify debugging for users
who aren't aware of OMAPI's logical channel limitation.
