Previously, the test ran a section with

  #pragma omp target thread_limit(4)

and expected it to execute exactly 4 times, even though it would
in practice execute min(cores, 4) times.

Add an explicit call to omp_set_num_threads() before that section,
making sure that this executes the expected number of times,
while still testing the functionality of the thread_limit() clause.
