This damn "translation" function has always been broken in some sense,
and your patch will just shift for whom it works and for whom it
doesn't.

The proper fix for this issue is to create a translation table that
maps between the system's handles and what we send over the wire.
That's the only way we can assure compatibility with all PC/SC
implementations (and the different versions of pcsclite would have to
count as several implementations as they keep changing how the handle
is generated).
