bsc: Don't start virtual SMLC in TC_lcs_loc_req_without_smlc

The SMLC is not needed at all in that test. In fact, we want it to not
be available. Starting it now within that test, where the BSC Lb link is
teared down (f_vty_enable_smlc(false)) may create race conditions where
the SMLC ttcn3 code (BSSMAP_LE_Emulation) will try to get the RESET
procedure ongoing, which the BSC SCCP stack may reject (SCCP UDTS) due
to the SCCP User being unbound during the VTY command above to disable
the Lb Link.
