The perf_test does not check the number of iterations and threads
when it is zero. If nr_thread is 0, the perf test will keep
waiting for wakekup. If iteration is 0, it will cause exception
of division by zero. This can be reproduced by:
echo "rand_insert 0 1" > /sys/fs/bcachefs/${uuid}/perf_test
or
echo "rand_insert 1 0" > /sys/fs/bcachefs/${uuid}/perf_test
