For CCCH PDUs which contain the L2 Pseudo Length IE, the working length of the
PDU was wrongly decremented by 1 while dissecting the L2 Pseudo Length, so
subsequent IEs were dissected 1 octet short.
This bug has apparently been present for a long time (before the gsm_a_...
files were split).
The problem was hidden by the use of the ELEM_MAND_V() macro, which was really
not appropriate here. I have eliminated this use of the macro, and removed
some collateral ugliness form the code.
