vlr_lu_fsm: drop unused out_state INIT -> WAIT_IMEI

There is no state transition from INIT to WAIT_IMEI, only to WAIT_SUB_PRES.

If there were code to skip WAIT_SUB_PRES, the allowed state transitions would
have to be the same as for WAIT_SUB_PRES, i.e. also WAIT_IMEI_TMSI and
WAIT_TMSI_CNF. For now just opt for the status quo.
