The SSB nFAPI message is only sent every 8 frames, and automatically
repeated by the PHY layer in between. This commit sets the vrb_map
structure in those frames in between nFAPI so that the scheduler does
not schedule on such resources.

The phytest preprocessor schedules only one UE, as many RBs as possible
(largest continuous RB region), with a fixed MCS and time domain
allocation.
