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")

v3/v4:
  Add the synchronization between the main lcore and worker
  lcores to ensure lcores to free "common object" after all
  func callback finished. <David Marchand>

v2:
  Add the discription about adding missing frees for the
  main thread in the commit log. <Olivier Matz>

v1:
  The initial version.
