[PATCH v6] mempool/dpaa: update for new mempool cache algorithm

["Morten Brørup" <mb@smartsharesystems.com>]

As a consequence of the improved mempool cache algorithm, the mempool
driver was updated to not modify the mempool cache's flushthresh field,
which is now obsolete, and modifying it has no effect.
