scd: Enable card removal check after select_application.
* scd/apdu.c (open_ccid_reader): Fix error handling of ccid_get_atr. * scd/app.c (select_application): Always kick the loop if new APP. * scd/ccid-driver.c (ccid_open_usb_reader): Don't setup at open. (ccid_slot_status): Setup interrupt transfer when !ON_WIRE.
We can use the interrupt transfer to be notified about card status
change. In this case, we don't need to issue PC_to_RDR_GetSlotStatus
command. This change improve the setup the notification; it should be
done after registration of APP.
When the setup is done just after opening the USB connection (before
issuing PC_to_RDR_IccPowerOn), a reader might notifies about no card
availability (because of not yet powered on), even though the card is
ready to be powered on.
