Subject: [PATCH] mbuf: fix debug checks for headroom and tailroom

[ upstream commit 814baffdb6910c1a949bd7c5ce3c6807f703c799 ]

rte_pktmbuf_headroom() and rte_pktmbuf_tailroom() should be usable
with any segment, not only with headered ones, so is_header should be 0
when we call for sanity check inside them.

Fixes: af75078fece3 ("first public release")
