scd: Fix RESET command handling (more).

* scd/app-common.h (struct app_ctx_s): Add reset_requested.
* scd/app.c (app_reset): Locking APP, set reset_requested.
(deallocate_app): Release the lock.
(release_application): Add LOCKED_ALREADY argument.
(scd_update_reader_status_file): Hold the lock when accessing APP.
When reset_requested is set, close the reader and deallocate APP.
* scd/command.c (open_card_with_request, cmd_restart): Follow the
change of release_application.
(send_client_notifications): Here it calls release_application holding
the lock.
