When reserving a specific memory amount, it was possible to pass
the first allocations and fail on a later allocation
where there was no check, resulting in a crash.
It is fixed by stopping the test if allocation failed.

When running on limited platforms like GitHub Actions,
the functional unit test "hash_readwrite_func_autotest"
will hit a timeout, especially when running with UBSan:
46/102 DPDK:fast-tests / hash_readwrite_func_autotest TIMEOUT 30.01s
killed by signal 15 SIGTERM
Similarly to what was done in the
commit fd368e1982bc ("test/hash: test more corner cases"),
some constants are decreased.
In order to keep the performance test as it was,
a multiplier is kept for performance test case only.
