[v2,2/5] test/hash: remove duplicated test code

  The test case target 'hash_readwrite_autotest' is covered by
'hash_readwrite_func_autotest' and 'hash_readwrite_perf_autotest'.
Hence, it is removed along with its test code.

I can see that DTS references this test:
https://git.dpdk.org/tools/dts/tree/tests/TestSuite_unit_tests_eal.py#n164

Travis (and UNH) also runs those unit tests (via the list included in meson).

Is there a reason to keep those in DTS?


Thanks.

I will take this as a no and go ahead with this patch.
