[ upstream commit d5559ac589953fa9f018aa581032e0f74bd49729 ]

Function reentrancy test limits maximum number of iterations
simultaneously, however it doesn't free the 'fr_test_once'
memzones after the fact, so introduce freeing 'fr_test_once'
in ring/mempool/hash/fbk/lpm_clean.

Meanwhile, add the missing free for test case on main thread.

Fixes: 104a92bd026f ("app: add reentrancy tests")
Fixes: 995eec619024 ("test: clean up memory for function reentrancy test")
