SCardTransmit returns SCARD_PROTOCOL_ANY as the receive protocol

[emaxx-google]

When the SCardTransmit function is called (either from JavaScript or from the NaCl client wrapper) without specified the desired receive protocol (this parameter is called pioRecvPci in the PC/SC-Lite C API), then our NaCl port returns with specifying the receive protocol as 3 (that is, SCARD_PROTOCOL_ANY) instead of the actual protocol (e.g. SCARD_PROTOCOL_T0).

This should be fixed. Note that the severity of the bug seems to be low as arguably this output argument is ignored by a typical middleware application.
