this patch fixes segmentation fault in pmd_cyclecount_bench_ops
function in case when state->opts->nb_descriptors is not
natural multiple of burst size.
To reproduce run: dpdk-test-crypto-perf with params:
--ptest pmd-cyclecount --pmd-cyclecount-delay-ms 5
--devtype crypto_qat --optype cipher-then-auth
--cipher-algo aes-cbc --cipher-op encrypt
--cipher-key-sz 16 --cipher-iv-sz 16
--auth-algo sha2-256-hmac
--auth-op generate --auth-key-sz 64 --digest-sz 32
--total-ops 10000 --burst-sz 255 --buffer-sz 1024 --silent
Fixes: 96dfeb609be1 ("app/crypto-perf: add new PMD benchmarking mode")
