t5330: remove run_with_limited_processses()

run_with_limited_processses() is used to end the loop faster when an
infinite loop happen. But "ulimit" is tied to the entire development
station, and the test will fail due to too many other processes or using
"--stress".

Without run_with_limited_processses() the infinite loop can also be
stopped due to global configrations or quotas, and the verification
still works fine. So let's remove run_with_limited_processses().
