[dpdk-dev] [PATCH v2] lib: fix unnecessary double negation

[Ciara Power <ciara.power@intel.com>]

An equality expression already returns either 0 or 1.
There is no need to use double negation for these cases.

Fixes: ea672a8b1655 ("mbuf: remove the rte_pktmbuf structure")
Fixes: a0fd91cefcc0 ("mempool: rename functions with confusing names")
