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

Browse source 
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.
