[PATCH 00/20] pktmbuf free bulk cleanups

[Stephen Hemminger <stephen@networkplumber.org>]

Looking at one driver noticed that rte_pktmbuf_free_bulk
was not being used. That motivated me to make a coccinelle
script to do a tree wide cleanup.

Then noticed that callers were having to check for NULL
before calling rte_pktmbuf_free_bulk, so changed it to
handle NULL array similar to free() and rte_free().

Do another tree wide pass to fix that and catch some
other unnecessary null checks in code.
