vlr_lu_fsm.c: don't send LU reject twice
Don't call tx_lu_rej() in the "vlr_lu_compl" FSM. It is always getting
called in the parent "lu" FSM and is therefore redundant:
_vlr_lu_compl_fsm_done(fi, VLR_FSM_RESULT_FAILURE, cause)
-> osmo_fsm_inst_state_chg(fi, LU_COMPL_VLR_S_DONE, 0, 0)
-> vlr_lu_compl_fsm_dispatch_result()
-> lu_fsm_wait_lu_compl()/lu_fsm_wait_lu_compl_standalone()
-> lu_fsm_failure()
-> lfp->vlr->ops.tx_lu_rej()
I have noticed the bug with the TTCN3 tests. This patch fixes
TC_lu_imsi_auth_tmsi_check_imei_{nack,err} after stricter checking
in [1] and also TC_iu_mo_crcx_ran_reject.
