Since it is a fix,
Updated the git commit as follows and applied to
dpdk-next-net-eventdev/for-main. Thanks
eventdev/crypto: fix multiprocess issue
Secondary process is not able to call the crypto adapter
APIs stats get/reset as crypto adapter memzone memory
is not accessible by secondary process.
Added memzone lookup so that secondary process can call the
crypto adapter APIs(stats_get etc)
Fixes: 7901eac3409a ("eventdev: add crypto adapter implementation")
