Remove usage of emulate_l1 flag at gNB

Browse Source 
The usage of this flag in the L1 is simply wrong: either, the NFAPI mode
runs L1, or not. Correspondingly, add an assert to check this invariant.

In the NR_IF_module, the correct check to do is for VNF (implying no L1,
or "emulation of L1" [which is not true]), in which case we use
queues.
