libopensc: SM: not all the APDUs need to be wrapped 

For some cards some APDUs are always transmitted in a plain mode,
even if SM session is opened.
For these APDUs the 'get_sm_apdu' card's handler returns SUCCESS without wrapped APDU version.
In such cases 'transmit' is called for the plain APDU.
