Function reentrancy test limits maximum number of iterations based
on the number of memzones and cores, however it doesn't free the
memzones after the fact, so on a machine with big amount of cores
the tests will fail due to running out of memzones.
Fix this by introducing cleanup functions for ring and mempool
reentrancy tests.
