When releasing Tails 3.6.2 I mistyped my smartcard's pin for the 3.6.1
UDF, and since the loop was aborted I continued manually. And since
doing anything "manually" is error prone I of course messed up: I
completely forgot about updating the 3.6.1 UDF.

So let's try to avoid this happening again by making this loop not
abort on a single mistyped pin.
