[PATCH] ifd_atr_parse() fails with some ATR strings

[stelian]

The following ATR string is not recognized as valid by ifd_atr_parse(): 3B 80 80 01 01

pscs-tools' ATR_analysis says the following about this ATR:

$ ATR_analysis 3b 80 80 01 01 ATR: 3B 80 80 01 01 + TS = 3B --> Direct Convention + T0 = 80, Y(1): 1000, K: 0 (historical bytes)

TD(1) = 80 --> Y(i+1) = 1000, Protocol T = 0

---

TD(2) = 01 --> Y(i+1) = 0000, Protocol T = 1

---

+ Historical bytes: + TCK = 01 (correct checksum)

Possibly identified card (using /usr/share/pcsc/smartcard_list.txt): 3B 80 80 01 01
