[v2] lib: fix unnecessary double negation
Checks
Commit Message
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")
