Workaround for handling 2 SS0 occasions per slot

Search Space 0 monitoring might depend on SSB. In !3332 this dependence
was removed by moving the configuration of SS0 earlier in a workaround
to avoid a segfault in handover. Now, a new workaround is needed to
handle 2 search space occasions per slot.
