[dpdk-stable] [PATCH] app/test-crypto-perf: fix missing bounds check on socket id

[Bruce Richardson]

The socket_id is used as an array index so should be within the range
of zero to max numa nodes. Add a range check to ensure we don't get
excessive values.

Coverity issue: 336812
Coverity issue: 336829
Fixes: 2c59bd32b70d ("cryptodev: do not create session mempool internally")
