scd: Fix resetting CARD_CTX.

Browse Source 
* scd/app.c (deallocate_card): Don't call scd_clear_current_app.
(card_reset): Reset ctrl->current_apptype.
* scd/command.c (open_card_with_request): Likewise.
(send_client_notifications): Likewise.
(scd_clear_current_app): Remove.

--

It's too late to call scd_clear_current_app from deallocate_card,
because CARD_CTX is already reset.
