fix inter-BSC-HO-incoming for AoIP (1/2)
Move the HO_ST_WAIT_MGW_ENDPOINT_TO_MSC state up to right after the lchan is
done establishing. For AoIP, the local RTP address towards the MSC already
needs to be known before the Handover Request Acknowledge is sent, so the AoIP
Transport Layer Address IE can be included. This patch only modifies the
handover FSM, a subsequent patch adds the IE.

Resetting at least fixes TC_ho_in_fail_no_detect, probably the others as well
