[PATCH] malloc: respect SIZE_HINT_ONLY when looking for the biggest free elem

[Darek Stojaczyk <dariusz.stojaczyk@intel.com>]

RTE_MEMZONE_SIZE_HINT_ONLY wasn't checked in any way,
causing size hints to be parsed as hard requirements.
This resulted in some allocations being failed prematurely.

Fixes: 68b6092bd3c7 ("malloc: allow reserving biggest element")
