PCSC: Accept 0x67 (Wrong length) as a response to READ RECORD

It looks like some USIM cards respond with 0x67 (Wrong length) instead
of 0x6c to 00 b2 01 04 ff. This was getting rejected in
scard_get_record_len(). ETSI TS 102 221 is not very clear on this
detail, but it looks fine to accept the 0x67 error value, too, to learn
the record length.
