scd: Fix receive buffer size.
* scd/apdu.c (send_le): Fix the size, adding two for status
bytes to Le.
--
Backport of master commit: 5c2db9dedf
This is long standing bug. So far, Le was not exact value.
Since forthcoming change will introduce exact value of expected length
of response data, this change is needed.
