Move ksft_set_plan() below the setup check. Also, when the underflow check fails, or munmap() fails, test_underflow() jumps to err_cleanup and exits without reporting the remaining results. Report the munmap() failure as a test result and skip the final HugePages_Rsvd check in err_cleanup, so the output always contains the planned 3 results.
