In monolithic, the sched_response mechanism ensures that FAPI messages
for one slot are not overwritten by scheduler instructions for the
following slots (i.e., it is like a memory allocation pool).
The allocation happens in nr_schedule_response(), not used by the PNF.
Hence, only deallocate when in monolithic.
The PNF uses a big ring buffer over all slots in a frame to ensure the
same.
