Each test case initializes its hash parameters in the test case
function. To be consistent, generate keys function should initialize
hash parameters similarly.

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).

Each test case initializes its hash parameters in the test case
function. To be consistent, generate keys function should initialize
hash parameters similarly.

This patch impacts the memory allocations, it should be placed before patch 2.

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
[Honnappa] Thanks for the review. I fixed these and few more in V2.

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).
[Honnappa] This can be considered as initialization code. I have left this as it is.

In this function, there are three other places returning -1 without freeing

Variables of size 128B can make use of stack instead of dynamically
allocated memory.

v3
  - Allocated pos on stack as it is just 128B
