vlr_lu_fsm: fix missing event for IMEISV
Event VLR_ULA_E_ID_IMEISV is listed as permitted in VLR_ULA_S_WAIT_LU_COMPL,
but is missing from the switch() on the incoming event. So, sending an IMEISV
identity during the WAIT_LU_COMPL state would crash osmo-msc.
When receiving an IMEISV, vlr_subscr_set_imeisv() in turn calls
vlr_subscr_set_imei(), so as far as the lu_fsm is concerned, receiving an
IMEISV is identical to receiving an IMEI, and it can continue to send a Check
IMEI request to the HLR. Thus simply add VLR_ULA_E_ID_IMEISV to the
VLR_ULA_E_ID_IMEI switch case.
