fix(ts_51_011): apply correct access conditions length

Browse Source 
When the access conditions are extracted from resp_bin, the wrong length
is used and only 2 bytes instead of 3 are extracted.

3GPP TS 51.011, section 9.2.1, table below "Response parameters/data
in case of an EF", clearly states that the length should be 3 bytes
(position 9-11)
