[PATCH 2/2] test/hash: reduce time of functional R/W test

[Thomas Monjalon]

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.
