Handover Request: also parse Chosen Algorithm IE, pass to lchan activation
During inter-BSC-incoming, the MSC sends the chosen encryption algorithm in the
Handover Request message. Actually parse this Chosen Encryption Algorithm IE.
Place the chosen algorithm and the CK into lchan_activate_info->encr so that
the new lchan will use the same ciphering on this new BSS as it did on the old
BSS.
