Subject: [PATCH] Fix dead lock in smartcard

    when smartcard_GetStatusChangeW_Call is called with infinit timeout during smartcard logon,
    we does not have access to cancel field used by smartcard_call_cancel_context
    We have to use smartcard_call_context_signal_stop which set the event stopEvent
    parsed by smartcard_GetStatusChangeW_Call
