card related bug 419 fixed

[Werner Koch]

Hi!

we had sometimes serious problems in gpg storing keys on the card as
well as other failures.  I have now figured out the faulty bit. The
patch below should fix it.

	* ccid-driver.c (ccid_transceive): Arghhh.  The seqno is another
	bit in the R-block than in the I block, this was wrong at one
	place. Fixes bug #419 and hopefully several others.
