I inspected this test a little more, I can see other leaks.
- generate_keys(), on error, we are leaking tbl_rwc_test_param.h.
- test_rwc_reader(), we are leaking pos.
- test_hash_readwrite_lf_main(), we are leaking
tbl_rwc_test_param.keys_non_shift_path

Looking at your patch 1, I would prefer you reset tbl_rwc_test_param field
per field to NULL once the rte_free() is called.
It would then be easier for you to track the remaining leaks (and patch 1
disappears).
