cosmetic: fix naming of GSCON_EV_A_CONN_REQ -> GSCON_EV_MO_COMPL_L3

The N-CONNECT.req on the A interface is a possible *consequence* of the event
being handled, namely the incoming RSL ESTablish INDication containing the
Complete Layer 3 message: dispatched by bsc_compl_l3().

If an (LCS related) connection is already present on the A-interface when the
lchan is established, there will be no N-CONNECT but an N-DATA sending the
Complete Layer 3. See BSC_Tests.TC_cm_service_during_lcs_loc_req().
