[dpdk-dev,v2] app/test-crypto-perf: fix uninitialized scalar variable
Checks
Commit Message
Fix problem with uninitialized nb_cryptodevs variable by
initialize it with 0 value. Program could jump to err label
without running cperf_initialize_cryptodev() function. Also assign 0
value to nb_cryptodevs after cperf_initialize_cryptodev() when value is
negative.
Coverity issue: 141073
Fixes: f8be1786b1b8 ("app/crypto-perf: introduce performance test
application")

v2:
* When nb_cryptodevs is negative after cperf_initialize_cryptodev()
assign 0 value to it.
