When mbuf debug support is turned on in the build time config, crashes will occur when clearing up the RX/TX rings, if the 10G vector PMD is in use. This error can be reproduced using testpmd. This patchset makes the setup/teardown code easier to debug by marking "cold" code paths as such, and then fixes the errors by checking for already-freed mbufs when clearing the rings.
